For me it is very much an issue of respect. Christian do not respect my lack of belief in their god. They go a step further and even tell me to my face (literally) that I am going to hell. The problem is that Christianity is irreconcilable with the whole "live and let live" stance. They can not let me live life the way I want it to. They believe I am living in sin and, therefore, not desirable person to be around ("be not unequally yoked together with unbelievers"). They are, therefore, disrespecting me and my beliefs.
There are several axioms inherent to this position that are simply not true. Firstly, there is an implicit notion that "respect" of one's positions is a good thing. This is questionable, and contingient on the way one defines "respect" (which I find to be a word that is too ambiguous to be useful in this context).
We can all agree that there are some opinions that do not deserve any "respect". For example, does anyone here "respect" the opinion that it's ok to have sex with children?
I have no "respect" for theist positions except in that I "respect" their right to hold them, as idiotic as they may be. This does not translate into any other form of "respect" that is often called for by individuals who are uncomfortable with my disdain for their beliefs.
What they are, in effect, asking for is a form of agreement
and only couching it in verbiage that hearkens unto some ambiguous ideal of "respect". That is not on the table, I will no more agree/respect a religious position that I find equivocal than I will agree/respect a 3-year-old child's position that the moon is made of cheese.
Respect for the individual is a wholly separate issue. I may, for example, decide not to try to win an argument with said 3 year old over the composition of the moon because it's unimportant to me and not worth causing friction.
By asking that people mitigate their religious fervour here is to ask that they respect your own desire not to hear it, it has nothing whatsoever to do with respect for your beliefs. It's merely a request that they do not use words that bother you.
And on the internet I see this nearly daily, and wish that people would more accurately delineate between wanting others not to bother them and with ambiguous ideals like "respect".
I "respect" the right of others to hold and vociferate their opinions. I also reserve the right to hold no respect, and disdain if merited, for their positions.
If "respecting" people's positions here means to not oppose the positions then I am afraid the axiomatic goodness to "respect" needs to be revisited.
I have no respect/agreement for theism the position, and don't expect any theist to act any differently.
Incidentally, yes, the ultimate elitism of thinking that those who think differently from you will burn forever is not nice. However it's not a matter of "respect" to me at all, nor is it something that bothers me too much given that I think their imaginary playgrounds of heaven and hell don't exist. It's merely a comforting delusion to them, and they are welcome to it.
