They were all smart men but cussing was part of the culture - as was drinking.
I don't admire cussing. Wish I hadn't picked it up. Much easier to start the habit than to lose it. But while I wish I would stop it entirely and wish others would refrain, I was immersed in it for most of my adult life. And many of those men were outstanding men, worthy of respect.
I can think of other things in the modern world that bother me much more - many of which could be fixed by making it legal to punch an asshole in the mouth!
I like the way you think!
