Aw, zoii, don't feel like you have to have everything figured out right now. Your views will probably shift in different ways as you grow, like everyone's do, but that's a good thing. When I was 6, I believed some pretty crazy things! And when I was 8, I thought how silly my 6 year old self was. And now... you guessed it, now I think my 8 year old self didn't know anything at all!
I'm not trying to say that the things you believe are silly (far from it!) but I'm saying that when our views change, it's usually a result of maturity happening. Some things that seem inconceivable right now might make more sense down the road.
The bible says something really cool, about how God will continue to improve us and show us where our attitudes are not the ones He wants us to have. I personally hope that you
never change for another human being, or have a specific view just because someone told you that it was right... but that God Himself helps you grow into whatever He wants you to be, and reveals truth to you in a wonderful way, and heals whatever hurts you have in your heart right now. When that happens, zoii, my sister... you won't want to argue. It's the best thing ever. Ask Him to guide you to the truth, if that's what you want to do, and then please relax. Rest in Him and know that He wants the best for you, and that all of the things you mentioned in your post really don't need to be fully understood right now. Be you, and seek Him. I believe everything else will sort itself out if you do.
