Johnnny,
there are good people and people who don't know what that means. They come from every possible type of human, religious or not. Being religious has no bearing on whether a person is good or not. One thing I know about people is that most just go about their lives doing what they need to do to get by. Some find a need to go around telling others how to live their lives, what to believe and condemning those who don't believe the same as they do to a lake of fire or eternal torment.
I don't care what people believe but I do care when people go around judging and condemning others, Not everybody is strong in the belief. Those who are week may find being condemned disturbing and upsetting. So I will challenge some who profess to speak for god because those people are dangerous and can harm others. Some blow themselves up, some shoot innocent people, others start wars.
I have very strong beliefs and I have studied various religion, philosophies and spiritual paths. I like to discuss the subject. I like to challenge people who believe things that I find unsubstantiated. I don't subscribe to any particular system so I can look objectively at beliefs and see that flaws. So I express my feelings on many subjects. I understand that they are my views. If they offend others, that is their problem, not mine. It is OK to disagree, but there is no excuse for calling someone an idiot or a sinner because they don't agree with you.
