An insult to him might not be an insult to me. I am extremely cut and dry in my personality which to some is an insult. I don’t play party politic games for example, I look at data and psychology / sociology is what I do for a living. So when I say things it comes off to uneducated / unskilled / badly raised people as insults. It happens often, those types take things to extremes every time.Good rule just don’t insult anyone.
So like I said if someone goes hands on over insults then it’s their problem not the person saying the insult or something perceived as an insult. Fighting over words is probably the most immature and irrational thing you can do.
