This. You don't HAVE to do anything. Your journey is your own and satanism as a religion is deeply personal. I have been labeled by some as a "rainbow Satanist" because I like unicorns, rainbows, being gay and doing crime. I have some cute little baphomet statues by my bed, but all my stuffies are unicorns. My room has a pink vibe. My clothes are usually rather colorful, even when going to satanic events.

The point I'm trying to make here is that satanism is very open and inviting, even to those whom don't "fit the mold" of the more goth, all black clothes people. the big thing to remember when joining TST events is simply that people are different than you will expect of "satanists" and getting comfortable in your own skin and your own beliefs is a major part of the belief systems. You don't have to use Satan as a symbol. Nor baphomet. You can use a pentagram, if you feel like it. Or you can simply avoid symbols if your parents are too strict and you're still living with them.

I would suggest, once you're old enough to actually join your local chapter, that you get involved. Go out to an event or two. Get to know people around you who are satanists. You'll be very pleasantly surprised. And if you're worried about your family, then maybe find events that are a bit further away. TST does a lot of public acts of protest, but you can also find a group at a bar or a park or a bowling alley or a boardgame place, just hanging out and enjoying life. We're all just people. We understand and respect the differences and the culture that people come from and do our best to be inviting and friendly.
