Perhaps people just don't believe you'll believe it when they tell you. Perhaps they instead suspect you will argue the toss, back and forth, endlessly, like the proverbial muddy pig fight (that only the pig enjoys).

This belief could be wrong, but would it better explain the behaviour?

I do believe you are on point. Yet this is not exactly reddit or facebook and I'm not a baiting troll (as can be seen from my comment history etc.)

Anybody who uses that narrative as a point against men is stupid. Men were made to fight. We would be cavemen still if it weren’t for the competitiveness of males.

Raising "made to" in a discussion of evolution is missing the point. We are who we are because we survived the filters, but that doesn't imply any particular purpose or intent let alone that we have to stay this way.

You're probably right, but you might be underestimating the number of stupid people out there.
