The Left Can't Meme

 I posit that they could meme, but reality won't play ball.

They want to pretend that conservatives are hypocrites for pointing out that it's stupid to bring a gun to a protest and this is the best example they can find.

The McCloskeys didn't go to a protest--they were in front of their home, in a gated community, in which a gang of protesters had broken-into and were threatening to break into their home as well.

The other difference is that Pretti didn't go to a protest, he went to a police operation with the goal of interfering with it.

It's not that they can't meme, it's just that the situation cannot be memed without lying about it.  This ought to cause cognitive dissonance.
