Because it’s funny. His own AG stated he wouldn’t be fit to stand trial in a case regarding the classified documents he was illegally in possession of. I will fully admit I’m more Trump than not, but put up a funny Trump meme and I’ll laugh along with you. Last actual funny anti-Trump meme I can recall was one of those “Ladies, find yourself a man who looks at you the way Trump looks at Ivanka”. That actually generated a giggle. The shit I see nowadays is lazy “Orange man in jumpsuit!!! He go jail!”. That shit’s not funny, it’s dumb. I’ve seen some pretty dumbass Biden ones too.
