The ability to brush off the words of a respected superior (parent, manager, supervisor, etc...) is not equally distributed in the population. Female students have a disadvantage over male students, especially in fields that are male-dominated (such as CS or Physics), LGBT members are even more disadvantaged. They might have been in the 70s and 80s. In 2019, if a LGBT member makes some threats, the institution will usually cave. In the old times people could lose their job if they were found out to be LGBT. Today people lose their jobs if they are accused from an LGBT perspective.
Pretending the power dynamics are the same as in decades past is hypocritical. Parents, relatives, and rural societies can still be (and are) cruel against LBGT people. Major companies, institutions, the law, modern media, etc? Not so much.
Too many people champion LGBT rights, feminism, etc today only because it's the default in "polite society" and the circles of power. If it was 1970 they would have followed the then mainstream treatment of women/LGBT, either like sheep or to their advantage -- as in fact, the majority (their parents) then did. Doesn't matter if they're different people than their parents -- the hypocrisy and the mechanism is the same is the same.
Only few courageous people have written/spoke out for decades about such matters, and now people come and use them to pursue careers, or gain followers -- and even more so, many use those causes to be cruel to people and gain power and social capital, the same way they would use their privilege against women/LGBT back in the day...
It's like Kurt Cobain seeing all the BS jocks that put him down sing "Smells like teen spirit"...
As for the "lots of research", in social studies it takes time to catch up with society (and it follows what brings in grants). There was lots of research back in the day too...
