It's all been happening behind the curtains for years and years. You can run, but you can't hide. And once those children who have been home schooled, and indoctrinated into whatever prejudices you have ladled on them ...(like mixed marriages...come on) and then they enter society, in jobs, in cities, etc...they will be ill prepared to deal with reality. And in fact, may have a social whiplash and become exactly the people you don't want them to be.
You can try to keep your children behind lock and key, but one day they will leave the house and you can't keep an eye on them forever....god forbid one of them is gay, or perhaps fall in love with someone of another color. Or perhaps they will like sex....a lot.
You don't have to be afraid of me, but I am very afraid of you.
