I hate to say this, but while the Carter children's ideas are just as screwed up as their fathers, I think they turned out fine in the sense that they are contributing members of society.
As far as your comment about never being a liberal...well, you forget the other part of that famous saying (badly paraphrased and murkily attributed) but here it is again:
"Anyone who is not a liberal in his youth has no heart. Anyone who remains so as he matures has no brain!"
I'm mostly just kidding, but how one becomes a conservative can take many paths and there is no "perfect" way.
I have never been a liberal because of the nonsense they preach and because how much they hate and want to destroy things. It is people who have heart who do not become liberals as defined presently.
Interesting, but for my background, I just never had any chance of being a liberal. I grew up going to Catholic School for my entire life and then joined the military. I definitely don't hate liberals, but just don't think I could ever be one especially on their stance on abortion.
