Remember in 2016 there were LGBT for Trump?
It was absolutely insane!! No it doesn’t make sense, but there are always a percentage that are delusional, and sometimes they manage to convince others.
Probably there are people who actually believe they don’t deserve equal rights, this can be indoctrinated through religion, and religiousness in USA is VERY high.
There are probably also people who don’t see themselves as part of one of the groups even if they clearly are.
Remember the MAGA woman who was extremely surprised when her husband was expelled because he was an illegal alien? That’s how stupid people can be!
Because it’s “all the others” not “me” they think.
