Sooooooooooooooooo…. do I have to hate Christianity or am I now against all religion? BTW, Jesus existed. That’s a fact. It’s just a question of “was he a nutjob fanatic?” or “was he really the Son of God?” If you’re not going to believe in something, then not believe accurately.
Does everything have to be black or white? Why not simply disagree with Christianity and other religions instead of hating or being against them? It seems to me that hating or condemning other people for their culture or religion (as opposed to their behavior) is more of a religious trait than an atheistic one.
There is almost no reliable evidence outside the Bible for the existence of Jesus, but assuming he did exist, why must he be either a “nutjob fanatic” or a diety? There are many other possibilities. Perhaps you should do some reading on this subject? A scholarly annotated Bible might be a good place to start.
I do my best to be as accurate as possible in my non-belief. I hope you are as rigorous with your own philosophical system.
