What do you think of bikers?

I love bikers...as long as they're not Hell's Angels. Haha. It would suck to run into one of them and express my anti-war beliefs. I think that bikers are the image of freedom, and they have a good taste in music, and their style is really awesome and they have a really good outlook of life and really good personalities, but many people look down on bikers? Why is that?
