What should I do?

Maybe you should just have little conversations about what you believe. Just ask something like "What if God is a women?" or something like that. I read about that way of putting it in a book. I don't think my Mom approves about Wicca but she still lets me practice and lets me believe what I want. She still dargs me to Church on some Sundays though. I didn't tell my dad if I did I`d be dead(Not litterally) but I`d get yelled at and have the bible thrown in my face so I just don't tell him, but it's easier since my parents are divorced.

well, My parents and older brother are very religious as well. (My other siblings don't really care)
I was really scared to tell my parents when I started Wicca because of so many bad things said about it.
I told my Mom about 3 weeks after I started, she was really understanding of it.
At first she kind of was...worried, I suppose, but once I explained what it was, she was fine with it.
My Dad's all right with it too.
My brother doesn't know, and I probably won't tell him because he's realllly religious.

Anyway, the point of this comment was to say
you should take your time when telling others,
You may get a lot of looks and maybe even some not-so-nice comments from others but you have to learn to ignore that.
Your parents should understand if they are any good parents.
So just play it by ear and wait for the right time.
You'll know when it comes to you
