In the aftermath of heartbreak and crushing upset, people often look for signs, superstitions and conspiracies to hang their disappointment on. And on Wednesday, that’s precisely what happened regarding Donald Trump’s win in the 2016 election.

President-elect Trump delivered his acceptance speech in the early hours of November 9, 2016, a date which can be abbreviated as 11/9. If those numbers seem eerily familiar to you, you’re not alone. No sooner did Donald Trump finish his remarks than disappointed people on social media around the world began noting the numerical similarities between 11/9 and 9/11.

Of course, given that the September 11th attacks are widely considered the worst tragedy in American history, these comparisons are likely to offend many people. Nearly 3,000 innocent people lost their lives that day.

Please stop comparing the tragedy of this election to the tragedy of 9/11. Both are tragedies yes, but to compare the two is insulting. — the original pancake (@ryanitrotter) November 9, 2016

Some liberals, however, seem to feel that’s the only way to adequately describe what they perceive as the catastrophic nature of what’s just occurred.

On 9/11 a war began. On 11/9 that war ended. The terrorists won. Our country is now more like theirs. — Joshua Hale Fialkov (@JoshFialkov) November 9, 2016

It is eerie though that 11/9 is a mirror reflection of 9/11. — Dan Fogler (@mrdanfogler) November 9, 2016

While social media is now full of these sacrosanct comparisons, some are cautioning people not to get so carried away that they lose sight of what an analogy like this really means. And as Hillary Clinton and Donald Trump both call New York home, that’s an insult they will no doubt take to heart.
