If you're looking for a reason why most of us aren't conservative, it's because one of the loudest messages conservatives have is that people who are different, who violate *their* sense of what is normal or traditional or natural, are the enemy. Or at least, not deserving of the same rights and freedoms as they are.
They depict gay rights activists as "special interests" who want "priveleges" that are the rightful property of everyone else. To many conservatives, trans* and androgynes and crossdressers are, of course, making a mockery of God and are all out to corrupt and/or seduce them and their children. It's pretty hard to sympathize and agree with people who think you're an abomination.
To a conservative, "tradition" (theirs) and money are more important than people. They hold conformity, the flag, "traditional family values" where the father rules and everyone else obeys, and the military sacred, but not freedom of expression (unless it's theirs) or religion (unless it's theirs). They believe might makes right, and they have the might. They claim life is sacred while opposing abortion but not where it comes to protecting the environment or the lives of those already born.
I realize not all conservatives are like that... but I cannot agree with fiscal "conservatism" either, as it's been proven disastrous under both Reagan and W, and honestly just funnels more money toward the wealthy.
I'm a progressive. I believe we should all leave the world better than we found it. I believe it is better to be a healthy happy fish in a vast teeming ocean full of wonder than a big nasty shark in a choked polluted pond with starved and sickly prey to feed on.
I believe that we've reached the era where technology can serve humanity better if we shed capitalism. I'm not a communist, but I don't think our current system is sustainable either. I long for the end of scarcity economics, and value being put on things that actually matter and make people happy.
