I am old, borderline ancient.
In the 1950s, 1960s, on our black and white tv there were many films about 'Cowboys and Indians'. It was a non-PC time!
There would be a bar scene - tables and tables of men doing whatever they're doing - betting, drinking.
(There would be some wise-cracking prostitutes).
A man would stand up (believing himself to have been cheated), He would swing a punch - and Every Single Man in that saloon would stand up and punch someone. Every man there was aggressive, only waiting for someone to kick someone around so that they could join in.
Their aggression was innate, just under the surface.
No wonder I'm wary of men.
