Why do idiots answer questions about other people's religions?

They are doing this because they're trying to, I don't wanna say convert you because it sounds really strong, but convince you that their religion is the right one. If you're gonna ask a question you have to be willing to hear both sides of it. You can't just say that a person is automatically wrong due to their religion. Also, how do you know that the person answering your question has no knowledge of your religion. If you're asking a question and someone answers it, then you can't say they're wrong or don't know what they're talking about because you don't know the answer. You're the one asking the question. Religion is a hot topic and there's a lot of different beliefs and styles making it easy for others to fight over things. I hope this answer didn't sound like I was trying to attack you.
