Maybe the gay kissers should try Iran? They would be hung there or shot. (I’m not sure I’d try it in Alabama or Mississippi either).
I personally don’t care about what people do in the privacy of their own homes. But men or women kissing each other in public makes me gag.
Different countries have different rules. For example, it is OK to have a glass of wine or beer on the beach in Cayman, but you would be arrested for doing so on many Florida beaches.
