You're making a lot of broad assumptions about audiences. And "serious conversation"... My sibling in Satan this is c/politicalmemes.
These memes don't just stay on Lemmy either. They get reposted all across the internet, printed on stickers and posters and t-shirts. The UK just jailed journalists last week for the terrible crime of projecting a picture of Trump and Epstein together on a building during Trump's visit.
