I’d ask Erickson to indulge this thought experiment.

Imagine that you’re a Muslim man, or a man that many people in a Western country would mistake for being Muslim––a Sikh, a Syrian Christian, a Hindu from India. You live in London or Paris or Queens with a wife and a ten-year-old child. If you heard that Islamist radicals had just carried out an attack on your city, or your country, or even in another country, would you worry about a backlash?

Would you worry a bit putting your child on the bus to school the next day?

If you got to your place of worship the next weekend and hateful words were spray painted on the wall, might that make you feel less safe, or even a bit paranoid for awhile? Of course you would feel that way. One needn’t even ask actual Western Muslims to know that, though the overwhelming majority would tell you so if you did.

I think that when national leaders and prominent commentators publicly urge against a backlash, it has some marginal effect. I cannot prove it. I could be wrong. It may be that the kind of bigots who do these things are beyond anyone’s reach.

But experts believe there to be an effect.

“One thing that we did find in our polling,” Scott Keeter, Pew’s director of survey research, told the Justice Department, “is that there was a very clear sense in the data that President Bush’s statement to not blame all Muslims, to make distinctions and not lay upon the Muslim-American population for what happened on 9/11, seemed to actually make a difference.”

There’s no cost in trying to preempt a backlash.

And there’s something else too.

If you were a Muslim or a Sikh or a Christian of Syrian descent in Paris or London or Queens, sitting up at your computer after your wife and child had gone to bed, wouldn’t it make you feel a bit more safe, and experience a little bit less dread, if your Twitter stream and RSS feeds included a dozen people––a political leader, a few journalists, a blogger, six or seven everyday folks you follow––trying to inculcate the norm that it’s wrong and irrational and discrediting to harm or hate people like you?

That does help millions feel a little bit less dread.

I understand that conservatives are invested in the proposition that it is important to call radical Islam by its name and that any evasion on that point is political correctness run amok. But this is not that argument, and it should not be conflated with it.

Unfortunately, there will one day be another terrorist attack. When there is, no matter who perpetrates it, individuals who merely share an ethnic identity with them should not suffer. Public figures like Erickson can give comfort to these total innocents at a moment of understandable anxiety, and perhaps make it less likely that they will be targeted. Urging people against turning their anger against innocent people is not an unserious priority. It is a reasonable, pragmatic, decent act.

What’s unserious––or just plain wrong––is being rankled by it.
