[Controversial] Why are men getting hurt by men and women alike?

I'm fairly new to this platform, but in last week I have seen posts appreciating men and celebrating women

The posts have comments from men demeaning their own. I don't understand why. Who taught us to be like that?

I am a man, I have vulnerable self doubt thoughts, but I would never put down another human (any gender)

Is it something common on this platform?
