I also don’t like fish
I find that sushi is less offensive to me than cooked most of the time, so that’s one place to start. Still not something I’d actively seek out but if it’s what’s offered to me I can deal with it.
I also overall find freshwater fish to be more palatable, I enjoy fishing so if I catch some decent sized trout worth keeping I’ll eat them (it’s more for my wife, but if we’re already cooking it I’ll eat it)
My mom’s also not a fish eater, but can stomach flounder.
A lot of men’s fashion, especially formal wear, takes styling cues from military uniforms, the modern necktie descends from the cravats by some military unit (I want to say it was some mercenaries involved in some French war, but I don’t feel like looking up the specifics right now)
