"Sex and gender are the same; they are immutable; and there are only two of them."
"Every child has a right to a mother and a father."
"An individual can't change his race."
"China is the world's worst human rights transgressor and currency manipulator."
The immutability of gender was controversial in 1991, but okay.
I'm not sure how bringing up anti LGBT crowds typing things like "it's Adam and Eve not Adam and Steve" 20 years ago shows there was no controversy on the internet 10 or 20 years ago.
If you are correct that typing things like that was not controversial, it sounds like identifying as gay or LGBT was indeed controversial, putting false the claim that the internet was a free speech utopia where you could type anything and nobody would care.
