Just a random aside: If you think about it, this is kind of weird rule. Not everybody's into the same things. AFAICT it should be more like "Treat others as they want to be treated".
"Treat others as you want to be treated" fails when the other person prefers other things than you do. Like when your cat keeps bringing you the delicious dead mice.
"Treat others as they want to be treated" fails when you believe that other people want something they actually don't (and which would be obvious if you would try imagining yourself in their shoes). For example if you believe that women or blacks actually want to be treated as inferior -- and they may even agree with you if they are brainwashed by the society to believe so.
That is, you can go wrong both by ignoring existing differences, and by imagining nonexistent ones.
However, it does seem the latter at least leaves room for "oh, crap, I was wrong" and generally less certainty simply because most reasonable people realize that they cannot know another's mind. Hopefully.
