Be civil. On difficult subjects in particular, you should work hard at being diplomatic. (It helps to picture yourself speaking to a friend.)

When disagreeing, reply to the argument instead of calling names. "That is idiotic; 1 + 1 is 2, not 3" can be shortened to "1 + 1 is 2, not 3."

Assume good faith.

Eschew flamebait.

Please limit your use of uppercase; it looks like shouting and is hard to read.
