I remember when I was young (well, I sort of remember being young, it's all quite fuzzy) thinking that I thought salesman type men were so weird. By that I mean men who just hit on every single attractive woman, hoping to make a sale.

But what you're describing sounds like something different. Something I can't explain. I would think a salesman who is anti-LGBTQ+ would look at a woman wearing a rainbow shirt and think, "Okay, that's not a good lead."
