In my previous post about whether atheists should try to stamp out religion, I think I made the question a little more complicated than necessary.
What it really comes down to is this: There are two types of atheists, which (for simplicity) I'll call the "nice atheists" and the "mean atheists." As P. Z. Myers points out, it's absurd to call atheists "militant" since it's not as if they're burning down churches -- they're just criticizing religion. However, it's not unreasonable to suggest that some atheists are not very nice.
The difference between the mean atheists and the nice atheists is that the mean atheists think that religion is ninety-nine parts pure stupidity mixed with one part lying, opportunistic con artists. And they want to tell that to religious people whenever they're asked to "respect" someone's faith.
The nice atheists, by contrast, believe that religion is more complicated than the stupidity-plus-con-artists model and/or that we should at least make an effort to get along with religious people.
The fight between the two groups is this: When the mean atheists and the nice atheists get together, it's not so much that it annoys the mean atheists to be asked to play nice. It's more that they just want to be able to call the nice atheists names like "sniveling milquetoast" and the like. Y'know, while they're at it. Because when it comes right down to it, the mean atheists just want to have fun. And I respect that.
Because I'm a nice atheist. ;^)
This firmly tongue-in-cheek post is dedicated to all of the atheists who don't like to "respect" people's faith... ;^)
