This aversion to anger is more of an upper-middle class thing than anything else. you could tie it in with the cultural marxism tinkering of our society, but it started long before that
working class and poor men still punch each other on a normal basis; confrontation either leads to a show of face until one guy has a legitimate reason to back down, or a fight happens
the trend in the middle class has lately accelerated with the push against competition and contact sports
male fighting in a normal setting usually doesn't lead to serious psychical harm; in some poor cultures tho, face is only recovered with blood
Weird point for me to think about... I was always a poor kid who grew up around middle-upper-class families. I always felt like I had to physically prepare myself for things. Strange...
there is almost always an in-group out-group dynamic in humans that changes the rules...as apllied to the outsider ;>
I grew up in a mixed middle-class/working-class neighborhood, but the local culture was pretty blue-collar; this was also before the soccer mommies started dominating the political landscape, too
