I would say that a moral Liberal is a Liberal who believes the following:
Abortion is wrong.
Disarming crime victims is wrong.
Homosexual sex is wrong.
Redistribution of wealth from producers to parasites is wrong.
Find me a moral Liberal. You can't.
How long are you gonna give me to find one? ;-)
I'm not sure I want to start this, but I disagree. Most of us on FR have a pretty similar view of what morality is, but I have an ultra-liberal friend who engages in lots questionable sexual practices, abortion-loving, total atheist, but I would number him among one of the more moral people that I know.
Why? Because he has his set of beliefs, and follows them very strictly. He does not lie, he is good to people, he is a hard worker, he never wants to hurt anyone, I mean, a really good guy. He was raised in a completely atheist household, and so the beliefs he came out with are different.
I just looked it up: mor-al, adj. 1. of, pertaining to, or concerned with right conduct or its principles. 2. being in accordance with such principles.
(I am so going to get flamed for this...)
The assumption we are all making here is that OUR beliefs are the RIGHT ones. I'm just pointing out that somebody who has a different frame of reference for their belief system can still be a moral person.
