You just want to let everyone know that you don't believe in God, and you're pretending to have some logical reasons to back up your beliefs. But if someone dismantles any or all of your arguments, you'll just change the subject to something else, because your arguments don't even matter to you. So why should anyone else take them seriously?
What's illogical to don't believe in a book containing things as dumb as "the Earth is flat" or "You shouldn't eat rabbit" or "The world is 7 000 years old"?
