I really don’t know why. My guess is it’s a Venn diagram of older dudes who are retired and civil war buffs.

I’m also interested in the civil war and that’s a chuddy hobby. I’m interested from a leftist political perspective. There’s still a decent handful of lost causers in the forums. I once saw an online slap fight where two guys were trying to one up each other by naming increasingly bloody battles in which the other team got owned as some sort of gotcha.
