Okay, I'm really late to this party but:
Well yeah, most legendary tattooers are grizzled old men that are a little politically incorrect. You sound surprised by the way he speaks. Not sure if you're trying to make a criticism or just a statement...? Personally, as a woman, I find this whole idea of masculine spaces (like an old tattoo shop) to be a sort of mystical thing. I like going into old timey barber shops with my boyfriend and seeing how different it is from the unisex salons I go to. I think masculine spaces should be respected and appreciated, there aren't many places where a guy can be a guy anymore without judgment. If you don't like how these guys carry themselves or operate their shop, there's more than enough other shops to choose from. /rant
And rightly so for him to be judgmental. Just because he did it doesn't mean it's a good idea. It just means he's old enough to know better and wishes someone would have told him not to do it when he was a kid.
