If i donate food to an athiest homeless shelter would they reject it because CHRISTIANS DONATED IT?

First off-there is NO SUCH THING as an "atheist homeless shelter". Why on earth are you making such a point to draw such a division between atheists and Christians? Why don't you do the same thing with Muslims? That's where the real divisions come in.

What a nasty, uneducated and totally unchristian post!

There are no such things as atheist homeless shelters since the vast majority of shelters have been sop ashamed of people like yourself that they go out of their way to underline they are nothing to do with religion and are doing it for altruistic reasons!

People who post like you only talk of donating and never do it!

Sadly the only thing you are doing is disgracing God and ensuring your eternity will be spent with the devil!

I didn't even know there was such a thing. Just for atheists? Haha. Okay. Donate if you want to. I would. It would shine God's love. Don't worry about if they hate you or not, God should be your concern, not man. :)

Unless you patronise them and try to assert your beliefs about your religion in front of them, making your 'help' conditional, I don't think they would really care. If you are acting out of some hidden motive other than pure altruism , and if it conflicts with their personal ideas and interests then they are within their rights to reject it. However no one can speak on their behalf. Atheism isn't synonymous with anti-theism.

Are there atheist homeless shelters? Is that a thing?

Good Christians can always find out.

I remember a point in time where the poes were at least funny.

They would burn it in the name of Richard Dawkins.
