Some people will read the racist post and think it’s true, even though there’s no evidence for it, and even tho’ it appeared on an unedited football messageboard from someone they’ve never met!
They want to believe it, because it confirms their prejudices.
Racists, for example, know there are a lot of gullible readers on boards, chat rooms, Facebook, etc … so they use these platforms to prey on their prejudices.
It’s the new way to spread very damaging lies and propaganda. You can take as many identities as you like, say pretty much anything about anything, and if you tie a political scarf to it, even better – Brexit, BLM, immigration, Covid, anti-vax… etc., you’ve seen it all.
