exactly. and bigotry isn't limited to sex or race stuff.
people pretty much hate anyone who is different than them. even so called progressive inclusive hippie types... will express crazy bigotry towards groups they don't like based on crude stereotypes that are largely not true.
our brains love to generalize. They don't like treating people who are different than us as worth our acknowledgement and esteem.
not even. 1950s we had this idealized version that everyone was heterosexual, owned a home and had strict gender roles.
That shit is now all blown apart. And for most folks the complexities of it all are beyond understanding.
And it cuts both ways. I don't care about other people's genders and identities, but boy they care about mine. Gotten plenty of sexist slurs from queer/trans people based on my gender and lots of shitty assumptions. I'm bi, but I 'present' as a heterosexual dudebro, and it makes non-gender conforming people angry at me for some reason, also many insecure straight men and women. Only people who don't seem to care are people who are bi, or secure in their sexuality. Way too many people feel the need to do that though.
