This is how the world ended

This happened yesterday while I was in WalMart.

Male cashier with multiple tattoos (two of them are colored in with rainbow): How are you this evening?

Me: Pretty good. Starving, obviously. How are you?

Cashier: Not bad. I can't wait to get off my shift and get home to my boyfriend.

Woman behind me: Wait, you're gay?

Cashier: Yeah. . . ?

Woman: That's a shame.

Me: Why?

Woman: He seemed like such a wonderful man, it's a shame he's gay.

Cashier: Why is it a shame?

Woman: It's wrong! It's immoral, it's dis-

Me: Excuse me, but what's it to you if he's gay?

Woman: It's offensive!

Me: But how does it affect you?

Woman: What?

Me: Where exactly does it start to make sense that it affects you? A relationship is between 2 people, not 3.

Woman: *sputters a bit, then leaves without her food*

Cashier: . . . Wow, thank you.

Me: Ignorant people are the reason I claim to be allergic to the human race.
