It feels like only yesterday when lefties were falling all over themselves to determine the motivations of those responsible for the Boston Marathon bombing.

Oh, wait. It was only yesterday. Strange, then, how the tides have turned. Since learning that the suspected bombers are Chechen Muslims and not white Tea Partyers (sorry, Michael Moore), suddenly the Left is no longer interested in focusing on motive:

Our reaction to terrorism shouldnt be predicated on the demography of the terrorists. Sad that bigotry apparently obscures this simple truth — David Sirota (@davidsirota) April 19, 2013

Oh no? That’s not what you said earlier this week, pal.

While media is trying not to assert motive, you'll notice that nobody on TV is making ANY effort to respect a basic presumption of innocence — David Sirota (@davidsirota) April 19, 2013

If your reaction to today is excitement or partisan glee, you've lost your soul. The events of today & the past few days have been very sad. — David Sirota (@davidsirota) April 19, 2013

Serious, you guys.

Sad for the victims, sad for Boston, sad for America & sad for whole communities who will be wrongly blamed for the actions of individuals. — David Sirota (@davidsirota) April 19, 2013

Tweets/emails celebrating fact that suspects are (allegedly) Muslim suggests many white people were hoping that was the case. Question: Why? — David Sirota (@davidsirota) April 19, 2013

Wow.

The best part, though? Sirota’s not alone:

Shhhhh! We can’t talk about that!

My point has always been that you shouldn't make assumptions based on race.This proves it. What are you going to do – target all Caucasians? — Cenk Uygur (@cenkuygur) April 19, 2013

Tell us more, Cenk.

Branding terrorists as LOSERS, not villains, not monsters, not martyrs, not foreigners, not religious fanatics —> a win. — Ana Marie Cox (@anamariecox) April 19, 2013

Sure, trauma or ideology related to Chechnya could be the trigger, but could be Columbine-style stuff. Keep in mind. — Clara Jeffery (@ClaraJeffery) April 19, 2013

If bombers r from Caucasus, it shows futility of racial profiling for terrorists. These guys r the original Caucasians. #BostonMarathon — Cynthia Tucker (@ctuckerprof) April 19, 2013

Remember how much the Virginia Tech shooter’s Korean heritage mattered to his motive? Yeah, me neither. — Marc Ambinder (@marcambinder) April 19, 2013

Cambridge radicalization. Blue collar Inman Square radicalization. Pot-smoking radicalization. Internet culture radicalization. — Marc Ambinder (@marcambinder) April 19, 2013

There are a dozen plausible speculative radicalization memes. We go 4 Islamic radicalization (in the absence of evidence) because it’s easy — Marc Ambinder (@marcambinder) April 19, 2013

And lefties know all about taking the easy route.

Yes! RT @acarvin: This. RT @NPRinskeep: We are collecting dots. It's a day to be careful about connecting them. — Sally Kohn (@sallykohn) April 19, 2013

Those rushing to assume motives based on where these guys were from would be cautioning restraint if suspects were from rural Montana — Sally Kohn (@sallykohn) April 19, 2013

. @jamesmdowns innocent people dying is very very sad. And innocent people being blamed b/c of racialized assumptions is sad too. — Sally Kohn (@sallykohn) April 19, 2013

It is sad. Almost as sad as these clowns’ feverish backpedaling:

The people who've been aching for the #BostonMarathon bombing to be motivated by ideas they hate will now shame you for discussing motive. — Jim Treacher (@jtLOL) April 19, 2013

RT @lachlan Out: let's hope the terrorists are white. In: stop focusing on the terrorists' skin color, racists! http://t.co/rQ9GwC2y6w — Teri Christoph (@TeriChristoph) April 19, 2013

.@davidsirota is this a parody account — GregGutfeld (@greggutfeld) April 19, 2013

.@davidsirota: "shouldnt be predicated on the demography of the terrorists," said the guy who wrote he hoped they were white. @greggutfeld — Yes, Nick $earcy! (@yesnicksearcy) April 19, 2013

David Sirota really shouldn't have used that monkey paw to wish for white terrorists. — Frank J. Fleming (@IMAO_) April 19, 2013

.@AdamSerwer would you reacting the same if it was a right winger? If you can't say yes, it's time for some introspection — Harold Stickeehands (@StickeeNotes) April 19, 2013

What the hope-they're-white crowd really wishes for is a reason to treat their domestic political adversaries as enemies of the state. — James Taranto (@jamestaranto) April 19, 2013

Exactly.

Oh, my.

Don’t tell that to the Atlantic Wire, which tweeted out this festering fail pile:

Anti-Islam bloggers latching onto suspects' sparse biographical details as vindication http://t.co/9nzFu9CFVM — What Matters Now (@TheAtlNews) April 19, 2013

Time to get schooled:

brilliant, Elspy. So the left was wrong to keep pusing the "Rightwing Hitler Birthday Party" theory but you're still right @TheAtlanticWire — Everyone's Famous (@AceofSpadesHQ) April 19, 2013

No matter what happens, the Left is vindicated by all facts. @TheAtlanticWire — Everyone's Famous (@AceofSpadesHQ) April 19, 2013

And the right is always wrong, even when they're right. If they're right, they're right for the wrong reasons (h8). @TheAtlanticWire — Everyone's Famous (@AceofSpadesHQ) April 19, 2013

Plus they're very declassee to note that they were right because lord knows the political left is so restrained. @TheAtlanticWire — Everyone's Famous (@AceofSpadesHQ) April 19, 2013

.@theatlanticwire could have noted all the figures on the Left who were actually wrong… but instead it directs its wrath at those who… — Everyone's Famous (@AceofSpadesHQ) April 19, 2013

.@theatlanticwire … were unfashionably correct in their beliefs. Because, those beliefs were bigoted. — Everyone's Famous (@AceofSpadesHQ) April 19, 2013

.@theatlanticwire Bigoted in a way that the left's constant rightwing teabagger terrorist speculation were not. — Everyone's Famous (@AceofSpadesHQ) April 19, 2013

.@SeahawkBurrrton @greenfield64 right. Their no-evidence speculations were directed against the political right so no harm, no foul. — Everyone's Famous (@AceofSpadesHQ) April 19, 2013

.@greenfield64 so long as you're calling out people who got it wrong how about @NPR (rightwinger celebrating Hitler's birthday)… — Everyone's Famous (@AceofSpadesHQ) April 19, 2013

Yeah, how about NPR?

Network “real reporters” were also having a rough time facing reality. Can you blame them? Now that it’s clear that the Tea Party wasn’t behind the bombings, their narrative has been shot to hell:

LOL, @msnbc "regardless their motivations, we need to be careful not to paint a broad brush". — John Ekdahl (@JohnEkdahl) April 19, 2013

Hi, @DianeSawyer. You're downplaying the fact that the #BostonMarathon bombers are Muslims. Would you downplay it if they were Tea Partiers? — Jim Treacher (@jtLOL) April 19, 2013

Anyone up for a stroll down Memory Lane?

.@ABC News is now dancing around it. These guys were "radicalized." By whom? By what? They won't say. #Watertown — Jim Treacher (@jtLOL) April 19, 2013

Bob Schieffer is lamenting how little we know about this fugitive. "Is he in a cult?" Careful, Bob… #Watertown — Jim Treacher (@jtLOL) April 19, 2013

Hi, @bobschieffer. The fact that these guys are Muslims doesn't provide any clues as to their motive. Don't you dare say it does. — Jim Treacher (@jtLOL) April 19, 2013

The entire city of Boston has been shut down. The whole place. And @ABC, @CBSNews, and @NBCNews have no theories about why it's happening. — Jim Treacher (@jtLOL) April 19, 2013

.@BobSchieffer just said the word "jihadist." Before immediately saying, "They don't seem like the type." What's "the type"? — Jim Treacher (@jtLOL) April 19, 2013

If these had been Tea Partiers, the media would be demanding answers from Rush Limbaugh. But now it's an unsolvable mystery. #Watertown — Jim Treacher (@jtLOL) April 19, 2013

Does Detective Andrew Sullivan’s forensic expertise extend beyond women’s reproductive organs? Maybe the MSM should summon him for help cracking this confounding case!

It’s quite amazing. If by “amazing,” you mean “exactly what we’d expect from the Left.”

Okay. Blowing up a little kid in front of TV cameras is only terrorism if we know why the killers did it. Otherwise, it's just an oopsie. — Jim Treacher (@jtLOL) April 19, 2013
