Atheists: Can You Still Accept X'n Friends?

[paulpablo]

Though I guess not everyone here is an atheist, I am. I'm finding it harder and harder to remain friends with believers.
This question is directed at other atheists. So, if you reply, please state first whether or not you are an atheist. If an atheist, please also state if you are a Type 1 or Type 2 atheist, as defined below. :-)
Question:
As an atheist, do you find you are still able to be friends with believers?
What I've found is that there are 2 basic types of atheists:
1) Simply don't believe in god, but don't mind if others do
2) Don't believe in god because they think it's a dangerous fairytale

I am in the second group. My hunch is that people in the first group can still be friends with believers. 
So, more specifically: If you are a 'Type 2 atheist,' are you still able to be friends with believers? If so, doesn't it cause significant 'cognitive dissonance' (mental confusion/stress)?
Thx, D

If you consider friends to be people who you don't have sex with but you do more than just work with I don't have time for many friends in general at all unfortunately.

I've had sex with and worked with Christians and been friendly with them, just from my experiences in work I tend to get along better with people who have atheistic tenancies of belief and skepticism because there are less barriers of conversation as in things that are unmentionable.
One of my best friends in my last work place was an ultra ultra religious Muslim, I've never met a Muslim as religious as him since, I used to have a good laugh with him but definitely with a lot of things I had to be wary of mentioning without a doubt.  


Sometimes it can be things you forget that religious people believe that you shouldn't talk about if you don't want to be offensive.  I've offended a Nigerian Christian in work by mentioning dinosaurs, and I think I offended a Muslim when I said giant humans couldn't exist because of gravity and he said I was talking bullshit, possibly because the hadith mentions adam and eve as being giants, or maybe he had another reason for doubting what I was saying.
