My best advice is be sure you know your craft. Educate those who want it, or at least be supportive. Correct the misinformation. "No I am not a devil worshiper, (explain why and what you are)." Some people will not care to learn or listen, so you have to learn to walk away.
As a side note, I see no reason you need to hide. I also see no reason why you have to rush out and tell people. Keep that to yourself for some time, when the people who truly care are interested and ready, you will be able to tell them.
It takes two to fight, don't be one of them.
