Every college in America with the exception of sparingly few were founded on values which we don’t see as good anymore. Literally just about every institution in the the country too. If your litmus test for calling women stupid is if they join any org or group that at one point was classist or racist, then you may as well just say you think all women are stupid.
While I agree that many of the Greek Life Organizations were founded on morally wrong principles, there are some that weren’t. Some sororities were created to be more inclusive of women of other races, backgrounds, and religions, but, yes, they were created because the original groups would not let them join.
This sounds like a personal problem. I’m sorry you had a rough time, but please understand, these groups are literally just social groups for those who wish to join. I won’t talk on fraternities cause I think they’re bad as well, but the problems that exist in frats aren’t really problems in sororities.
