It's not your fault one bit. I'm sorry your mother is so unaccepting of other religions and non religions, as well as your resentment towards yourself and her. My mom still believes, though not like your mother, and told me that I need to raise my children believing in something, and that Christianity words things in ways kids can learn to be moral.
Even if it does, I'm sure I can do just as well. I plan to teach my children about different religions and nonreligions and let them choose for themselves once they are old enough to really understand what they are doing, as I didn't truly understand why I was completing sacraments until I was much older. As for telling her... My best advice is to make a list of pros and cons to telling her.
It might be difficult, but maybe telling her is the best choice. Do you think she can eventually get over it, or do you think she will never change her views, even towards you?
If your mother really is a true believer, then she should not hit you or hate you for not believing in God. I don't know if you've ever read the bible, but in the story where Moses leads the Jews out of Egypt by parting the Red Sea and then drowning the pursuing soldiers, the newly-freed slaves cheer at the deaths of their enemies. And then God says to them, "No, do not rejoice, for they are my children too".
According to the Christian's own holy book, God loves all humans, whether they worship him or not. My point is, if your mother is not a hypocrite, then she should know that her God loves you no matter what you believe, and she should do the same. As long as you're a good person, it shouldn't matter what your religious views are.
Hell, there are plenty of Christians that only do the right thing because they're afraid of God, not because they actually feel empathy for their fellow humans. Seeing as you don't have a god to be afraid of, when you do the right thing it's always for the right reasons. And for the question of whether or not you're at fault, you're definitely not.
The fact that you are logical enough to contemplate your beliefs and settle on proven facts rather than what the masses told you simply means that you are more intelligent than the majority of society. Ultimately, it's your decision if you tell your mother or not, but I think you shouldn't have to lie about who you are or justify your beliefs to anyone, especially your family. Your parents are supposed to love you unconditionally.
No one should have to pretend to be the child their parents want. If you tell her and she gets violent, there are numbers you can call, places you can go for help and protection. Even if she does get angry at you, isn't that better than living in fear?
Sorry for giving you such a long answer!
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
