Liberalism is the result of bad parenting. Period.
Nah, plenty of good conservative parents end up raising liberal children. It's not parenting that's determinative of the status of liberal.
Don't say that! I have one son that's as conservative as I am, one who doesn't go either way and apparently doesn't care about politics at all, and one other who is a liberal! He's a very loving young man and becoming very successful but he's been brainwashed by people around him who are important to him and he's against many of the things I hold dear. But, I still hold out HOPE for him.
.....and the Educational system, which has more access than parents do much of the time.
