What do you do when you are faced with someone who is intolerant, and even trashes your religeon?

I am having this problem on another message board, where I have had my religeon called "crap" a "fad", was told that I drink blood and am a lesbian(neither of which is true just so you know) and told that I identify as that only to be a cool goth kid.

For those wondering I identify loosely as wiccan.

Edited to add: I am neither a kid, nor a goth
