“I don’t want you catching gay. Come here and sit with me.”
“Get away from that person. I don’t want you getting lesbian.”
“I won’t let my kids play with that gay couple next door’s kid. They might catch gay.”
You can’t catch gay as easily as catching stupid. When was this possible? Do gay kids that hang out with heterosexuals catch straightness? I didn’t. If you could catch gayness and intelligence from others in this world would be much stupider (not a word by the way) or gay.
