No they dont encourage racism or normalize racist behaviour. I know alot of people who laugh at those memes but are not racist at all, like me.
If someone lets memes to change their behaviour irl, they have low brain capacity
HOW IS POSTING EDGY AND FUNNY MEMES OFFENSIVE (which have enjoyed in the past and still does)? And it attracts "bad" kind of people? Lol i dont think so, thats just bullshit
