It is not a problem to disagree with certain beliefs, it is the way it is framed that is the problem.
You can be a disbeliever, no problem but then one has to also say, ok i might not understand your belief. And I dont believe in a God. But acxept that others do.
Same as a believer should be open to hearing what non believers has to say.
By the way, it goes both ways.
I do accept that others believe in one (or more) gods. With a spectrum of definitions of "god". Are you under the impression that I do not?
I am suspecting (but am not insisting) .that is hearkens back to the fact that theists are not used to having their epistemological foundations not taken for granted; if not in specifics, then at the very least in category.
So here I am in a world of mostly religious people, where, from the time I am born, the vast majority of them have been constantly telling me that I only have value in reference to, and acceptance of, their theological cosmology. Some of these are soft sells through passive means. Some are passive aggressive - such as we see here. Some are hard sells - door to door, cold calling, chick tracts, stops me in the parking lot, in the grocery store, in waiting rooms, at the florist, billboards. watching Independence Day fireworks, waiting tables, and so many more.
So, I ask, Why do you believe what you do? How do you know what say that you know? Why should believe that you (or anyone) can know what you claim, or even have the ability to know such.
And BTW, those questions are not simply aimed at religious beliefs. I apply them to everything.
"I find that theists tend to have emotional reactions to being disagreed with, and see that disagreement as anger and militance, failing to recognize that it is merely dissent, just like the theist, who is as much in disagreement with the atheist as vice versa. But it is anger to the theist. You'll rarely see a secular humanist get angry at any theist for disagreeing with his worldview and values." --
