I admit it, I'm an idealist.
I know we don't live in an ideal world, but I don't think that means that I have to be content with the status quo, or that I shouldn't want something else (or strive to make changes to bring certain of those ideals into reality). I'm not willing to be passive about things that matter to me, and I don't think that's a negative trait.
My opinions, my ideals, are based on thought and study and testimony, not on ignorance or prejudice (though those words have been directed at me recently). I am not ashamed of them, nor do I feel the need to keep them to myself. I'm not trying to 'push' them when I share them, and I'm not trying to insult or offend people who don't agree or fit in with them. I do not expect everyone to agree with me and, in fact, I usually enjoy a healthy debate--so long as everybody is nice to each other and keeps the discussion on the topic rather than making it personal.
As I said, I realize that the world is not ideal. Many of my ideals are not or even cannot be realities here or now. That doesn't mean that they are bad ideals, or that I should stop believing in them, talking about them, or doing what I can to bring change to my world.
