For a lot of trump supporters, this is why they voted for him. He gave them a licence to be racist and sexist and bigoted, etc.
Al the things trump is, they are. And him being in office legitemises them. It makes them feel "heard" instead of "opressesed."
Granted (of course) hate speech and any form of misogyny or predjudice (all of the above) should be illegal. It should be "oppressed." But from their perspective, they aren't allowed to be what they are, and trump makes them feel like they can.
Its a devastating realisation that i came to whilst watching those trump rally videos where the comedians go and interview the attendees with the aim being ro let them mock themselves by being caught out in a web of contradiction.
When the interviewers say biden did x y z terrible things and the trump simps say "yeah because biden is terrible and an awful person and should be in jail" but then they pull the rug and say, "sorry, i read the wrong but, that was trump who did those things"
When faced with the fact that trump is the one who did all the awful things they suddely switch over like they are bipolar and say, oh well trump is perfect so i dont care that he did those things. Or trump had a reason that made it ok. Or oh, i did t know he did that, but im still gonna vote for him.
