This actually isn’t too surprising to me, personally. I’m an atheist and I follow a lot of atheist-related news sources. Same thing happens when atheist organizations try to donate money to charity. It’s not uncommon for charitable donations to be outright refused or accepted without any appreciation given.
The weed pimps in Colorado Springs is a nonprofit org geared to the cargiving of cancer patients who can’t afford there meds. I’ve donated a few units. The cool thing is all donations are tracked and both the patients and doner can contact one another if you do please. So no one stands to profit.
