I’ll agree with you except for the timeline. It started after 9/11, bigotry was far less openly acceptable during the 90s.
I want to disagree with this because bigotry was huge in the 90's, but so was attacking it. Our cartoon's were chock-full of anti-bigotry messaging, but then movies would be the opposite.
I think I, personally, would typify the 90's with saying that one out-group is ok, but only if we all make fun of another one or you're the butt of jokes. IE. You can have Will and Grace, but we're using 'gay' as a word to literally just mean 'bad.'
We'll have to make due with this, fellow Canuck.
