I don't equate people who disagree with homosexuality with hate. As a heterosexual, I personally find homosexuality rather odd and distasteful... but that is totally my personal point of view, and I don't let it affect my basic point of view that gay people deserve fair and equal treatment, just like anybody else.
No, I'm talking about real hate here. For example, people who picket the funerals of gay people with signs sayings "God Hates Fags." I'm talking about members of the Aryan nations who very nearly succeeded in a plan to bomb gay clubs in Seattle and Portland--an act that would have killed hundreds of people, including personal friends of mine. I'm talking about gay bashing--randomly attacking people and sometimes killling people who are gay or who appear to be gay. I'm talking about Jerry Falwell and Pat Robertson blaming gays (along with liberals, feminists, etc.) for 911. I'm talking about the 1996 Republican candidate for governor, Ellen Craswell, who was an unapologetic religious fundamentalist. One of her chief advisors had advocated that gays be deported or sent to concentration camps.
Now, THAT'S hate... and barely different from Hitler, either. Allen Craswell ended up getting 40% of the vote in "liberal" Washington State. The America I believe in is better than that.
At the risk of sounding repetitious, I do know that most conservatives do not harbor this kind of hate. But, it is still safe to say that this kind of hate comes primarily from the right-wing. For example, when Ann Coulter called John Edwards a "faggot" (a genuinely hateful word, whether used in jest or not), she was immediately condemned by conservatives like Mitt Romney, Rudolph Giuliani and John McCain. Because of this, if I'm debating this kind of issue, I never make assumptions about what individual conservatives believe, and if I hear left-wingers make generalizations like "all conservatives are anti-gay" I usually explain to them that they are completely wrong.
However, this is how I personally feel: I think that left-wing Americans have taken an enormous amount of crap for a long time: told that we are not real Americans, having our patriotism, our loyalty, our very legitimacy as Americans questioned. In my personal experience, left-wing Americans often have a problem with conservative politicians and conservatism itself, but we are much more sympathetic to conservatives as human beings. I know conservatives with similar points of view, but as I mention above, there is a whole cottage industry of people who are constantly attacking "liberals" as un-American. I've often heard my moderate and libertarian friends comment that there is much more hate from the right to the left than vice-versa. Now, that's all from my perspective, and I could be wrong--but I honestly don't think I am.
Anyway, my personal point of view is that, as a genuine "liberal" (which doesn't necessarily equate with "left-wing" at all), I enormously value political pluralism. I wouldn't want to see an America without conservatives... or without moderates, libertarians or anarchists either. I may disagree with people, but I don't want to see them disappear, and I don't think that ANY political group has all the answers on complex issues like the economy, education, social problems, etc.
The reason why I originally took you to task for bringing the whole "liberal" thing into this discussion is that I was defending hunting (at least, hunting for one's food), and this is a normal point of view for millions of liberal Americans. I've lived in NE New Mexico and the Puget Sound area of Washington States, and both of those areas are full of left-wingers and hunters... and very often left-wing hunters. I'm a gun owner and don't consider myself to be pro gun-control (unless you count things like background checks and the Brady Bill, which the vast majority of Americans support). Some of my fellow liberals support severe gun control or are anti-hunting? Granted, and I don't let a political label get in the way of openly disagreeing with them.
Anyway, I feel strongly that if you care about any particular issue, then you should welcome collaboration with people of any reasonable political persuasion--to assume that they disagree with you based on their politics is just to alienate potential allies.
