Before all this online psyops I think neither men or women would have cared about this.

This has always happened to women. I mean, men do it do men too, but other men counteract that by doing it too. As a cis man I’ve encountered way too many cringe worthy situations from my fellow men.

If you’re never experienced mansplaining you might now actually know what it is about.

Oh yes. Only men mansplain. It’s in the genetics.

Do trans men also mansplain? They’re biologically female, so they might be incapable.

It isn’t only men, it is just the biggest group.

Us men are taught that our opinion is always valuable. A noble goal I am sure.

But women still get too many “go back to the kitchen” comments whenever they give their opinion. From the more sleazy and sexist people around.

Yes, every person has the potential to mansplain, but the group that gets attacked for it the most (even if it is not called mansplaining) tend to do it less.

Us men are taught that our opinion is always valuable.

As a man I’ve been told no one wants my opinion since the 2000s so I’m not sure where you’re getting this from.

There’s that saying about equality in an unequal society feels like oppression. I think it applies here. Of course I don’t know your particular life circumstances but I would bet you’re being a bit hyperbolic.
It ever was? I was a kid back then, my opinion has never been valued and never will.
