An evergreen truth of comic book retail seems to be that the first customer on a Monday morning will be very lonely and want to talk to you about every possible subject that pops into their head.
So, this morning, just after I put up the My Friend Dahmer poster, the guy says "You know. I know he was nuts, and everything. But people forget that he grew up gay in a very religious household in the sixties. That will mess anybody up."
I Spock-eyed him. (Rock-eyed him?) "I know a lot of people who grew up gay in the sixties. They do have a lot of issues/ But none of them spent the nineties raping and murdering teenagers."
"I mean, you'd like to think that. But do you know? Y'know?"
"YES. I KNOW." ended the conversation, until he started yammering about Strong Female Protagonist, which, surprisingly, he didn't say anything remotely problematic about.
