Probably gonna get downvoted for this, but that’s a misleading headline. Nazi meme implies the meme itself is Nazi, where as the meme in question, according to the article, was comparing LGBT to Nazis.
I don’t agree with the meme, for the record, I just have (what I think is) a reasonably specific definition of Nazi. “Bigoted” would be a more accurate word to use here.
But then, this is Not The Onion, and the headline is technically correct (it’s a Nazi meme in that it’s a meme featuring Nazis,) so whatever.
