My experience in a Moon church/organization (korean religion)

Finally, this made me wonder. If there are missionaires of every religion, why not atheist missionaires? Not to profess atheism, but simply to interact with foreigners and have a good time together. I say this because my most precious time with them was when religion wasnt involved. Genuine human interactions, and not bullshit religion. 

Thoughts?

I imagine there are atheists get-togethers, support groups, etc, but of course calling it a missionary would be inaccurate.
