On top of what everyone has already said...I noticed the title of the thread.
There is no reason to expect Satanism to be accepted, in the way you seem to mean. If you are a Satanist, you will be feared. Expect no other response. Not to be rude; but, if you were to decide you would like to show what Satanism is about, you may decide that making a particular musical style your signature quality is not the best way to go about that. Just my opinion. Another idea...headphones.
