Is it normal I am antitheist?

I'm a Christian but I can completely understand where you are coming from. Both mormonism and Catholicism can be very strict and, well, too religiousy! What you are experiencing my friend, is a religion over load, people have beat things into your head and tried to force you to believe things that you weren't ready to believe in yet. God does not condone such behavior by his people, yet there are still some who claim to be his followers that try and force religion on people and harshly judge people who don't. Truth is, God doesn't want anyone to be forced to love and follow him. He wants you to willingly come to him. In fact, the bible tells about "the age if accountability." This is the time inna person's life where God reveals himself to you and you are presented with a choice... Follow Him and accept his free gift, or don't and suffer an eternity of consequences. Don't think that it is an act of evil that people who reject his son don't go to heaven. God physically cannot be around sin, which is why he sent his pure son Jesus to die in debt of our sins. Those who do not repent through Christ will be in a place where God's wrath will constantly remind them of their choices. It says in the bible that God weeps for each person sent to hell. So he wants you to go yo heaven, trust me, but on your own terms!

Let's not forget why we are here in the first place, God needs to be loved, he made us to share a loving relationship with Him. However, he gave us free will, he wants us to choose him over our desire for sin and other worldly temptations. What good would our love be to Him if He forced us to love Him? That's why we have free will! So clearly He doesn't want anyone forced into a "religion."
I don't believe in religion, God wants us to have a PERSONAL relationship with him, not go through a whole bunch of crap just to show everyone else that you're a Christian. That's not at all what it's about. Anything sounds bad if you make it sound judgmental and strict. See for yourself, don't conform with the crowd, look into it and make your own decision don't let anyone make it for you!

If this all sounds ridiculous to you, let me suggest a book written by a once avid atheist! This man is now a Christian, he proved Christianity to himself through science! The book is called "The Case for Christ" by Lee Stroble. Prove it to yourself, you be the judge and decide where you will spend an eternity.
