Lol. "Not all men" is factually correct and perfectly valid.

In fact, it's not even "most men".

And the idea that "all men" are somehow responsible for the actions of a few criminals is completely absurd.

Most of us have absolutely no contact with these people. How is anyone supposed to influence the actions of men they've never met, many of whom are sociopaths who would never listen to any advice they were given anyway.?

Absurd.
