If you don't want to pay any attention to the claims of Christianity, then by all means don't.
Stating that you are, quote, "seeking its demise", is the very definition of intolerance.
> 'Nothing above is even "disparaging", even that fairy tale remark. It's not disparaging to state that, without good evidence, you believe fantastic stories from thousands of years ago to be fairy tails.'
This is the very definition of disparagement.
If I were to refer to your atheistic beliefs as 'the ignorance of children, raised by a wicked society that is under the influence of psychopathic demons', would you view that as disparaging? Of course you would.
The difference between that way of viewing things and your way of viewing things is simply a matter of perspective. The difference is, one viewpoint is based on knowledge, whereas the other is based in ignorance.

Evangelizing atheism is no more intolerant than evangelizing your religion. Personally I have no particular interest in doing either, but if you get bent out of shape over somebody doing it, that's on you. If you don't like somebody disagreeing with your beliefs then move to a theocracy where such things are forbidden. The "intolerance" you describe is in fact an expression of the bedrock of liberal society.

Lots of people have claimed to be god. Some are even widely recognized as good people. Do we need to give them all our attention? Cause I'm pretty content living my life without believing in wild fairy tales.
