see, I think they will to some degree. Particularly re gay rights. It's amazing how many people default to conservative opinions but when some otherwise nonconfrontational person wears a rainbow badge or posts a pro-gay-marriage meme statment they change their mind. Even more so when a great number of their friends do it. I've seen it happen. They won't listen to some activist weirdo but when their "normal" friends just make little comments on their FB or whatever they jump on the bandwagon. As we know, bandwagon jumping becomes habit becomes ingrained opinion - that's how it works with the masses.
