It this a religion war in Y! Answers?

I come by so many people who bash and criticize other people by their religion. But people HELLO! Is it really our right to be judging and telling whats right or wrong? We all are imperfect and sinful and it's human nature. I'm sorry to say it but we are all stupid. That's why we need the Lord for guidance, wisdom, etc. You can't change another's heart so what’s the point to even try? First look what's in your heart before you judge other in their hearts. I mostly just what to hear your opinion. So please, share what you think. Best answer for whoever can give me a great point on this subject.
