I don't want to participate in my families religious practices
Why don't you want to participate?
It's insane to believe in a fictional character
Religion is a touchy subject for a lot of people. I think that if you are not wanting to be a part of it, that is all fine. Religion is not for everyone.
I get it. If it can make people happy then it's understandable.
I'm glad you are seeing religion from a positive angle now, even if it's not for you.
