Same reason why I actively advocate for civil rights and against racism even though african-american people were given their rights so long ago. I'm allowed to continue to fight until it's gone forever. Racism is a big issue in certain parts of the world, and I shouldn't be criticized for trying to fight for our rights.
See the thing is that you aren't fighting for people's rights, you're arguing on the internet about beliefs and ideals you're apparently well versed in enough to argue in their behalf but not aware enough to realize all the implications of everything you've said.
I'm all for equal rights but I'm not about to dedicate my life to fighting boogeymen like rape culture and the patriarchy that were invented by a movement struggling to stay relevant in modern society, one that also seems to be demonizing the opposite love because they need an antagonist to latch onto. The fact that you brought up the wage gap is really telling that you aren't playing by logic, but rather by emotions.
And that's their opinion and they have the right to say it.
There is nothing you can do until the constitution removes freedom of speech. Which apparently seems like what you feminists want.
Freedom of speech protects you from censorship. It doesn't mean you're entitled to your opinions. Nobody is entitled to their opinions. Your opinions are just personal beliefs, there is nothing in the nature of personal beliefs that make them credible and for the most part sharing critical, controversial beliefs is almost always going to be met with dissenting opinions in the public.
