This is the problem with society. If someone doesn't believe what you believe, you blow their belief out of proportion. To actually understand someone's belief, you should actually try to understand what their religion as a whole is.
1.) Atheism is not the belief of science or that science is the answer to everything. There are religious scientists out there too, not all scientists are Atheist.
2.) Atheism is NOT the belief in no deity. Atheism is the LACK of belief in a deity. That means Atheism is an open textbook as far as a religious topic goes. I'm Atheist, I have morales, I have a sense of dignity, pride, humiliation, just as a religious person does. If you tell me a god exists, I'm not going to say prove it, you're wrong, or any of that. I'll just say OK, a god exists. I'm not going to sit here and deny your belief. Reason being, I cannot disprove your god as much as you can prove it, so why would I stoop to the level of blatant insults?
3.) Atheists that actively try to disprove a god or religion is pathetic. Just because one isn't religious doesn't mean you shouldn't have respect. If you want to believe in a god, please do. If you want to be homosexual, please do. Who are you to decide how one can live their life? (unless you're trying to something messed up like murder, than please find the proper intervention/response team to stop that psycho)
4.) Science is NOT the fundamental grounds of Atheism and this is the one that really pisses me off. Never has a true scientist denied the existence of any religion through science. Science has a method of carrying out their experiments/tests, and that is called the "Scientific Method". In order to carry out this procedure, you must first ask a question. For the sake of this thread, our question will be "Does God exist?" Next step is to create an experiment, a list of steps on how we can prove or disprove this question. So once again, for the sake of this topic, our steps will be... Wait, how do we create a list of steps to prove/disprove a omnipotent, celestial being? The answer is we cannot. Since we CANNOT create an experiment to this question via the Scientific Method, that means IT IS NOT SCIENCE. Simply put, religion is not science. We can't say it's true or false because we simply cannot test it. Does that mean god does or does not exist? Well since it's not science, we can't give a definite answer to that question.
Honestly, people that attack one another or say their belief is preposterous, unlikely, unbelievable, unexplainable, etc. are in my opinion, the lowest of the low, the scum of the earth, the most despicable people imaginable, the ones that cause chaos and war within our world. People say it's because you are unable to understand their fundamental beliefs, but I view it as you're not even bothering to try to understand them, you're simply hating because you can.
