It's mainly Western Countries but yes I am speaking as an American because every stage of life men are harassed, and belittled.

I'm a western young man and I've never experienced such a socialization process, but I recognize personal experiences rarely represent reality.
However, the statement that an average western male will experience widespread and daily contempt, hate , harassment and threat is , fortunately , not supported by evidence.
That scenario assumes a world where most individuals have succumbed to bitterness and hatefulness for half the human population, which you won't find in the west, nor anywhere else. (Aside from the internet and political spaces, which I don't recommend frecuent)
Most people is normal. If people around you regularly make you feel worthless and threaten you, remember that that's not normal and you can definitely find good people, because they are the majority. You don't have to conform.
I will say most of it is anecdotal perhaps but from all the stuff I watched online growing up it seems like there's a lot of disdain for men in general.
Personally, people in my immediate life are strict with me, like my parents, I get critized very sternly sometimes by them.
