Cofty,
"Feed the hell out of it. Kids are always embarrassed by their parents. When their parents are shamelessly mocked for being utterly stupid, the kids with figure it out. Homophobic bigotry will drop by magnitudes in a single generation."
Disagree. The culture in which those kids are raised in reinforces/normalizes such thought and behavior in school and elsewhere. They're not going to be embarrassed by their parents unless perhaps they're living in a mostly liberal region.
I doubt that homophobia will drop anymore than racism has in the red states.
