Amazon.com has a mechanism by which you can help fund non-profits. Through this Amazon program, you can shop on a special Amazon page and Amazon will donate to a charity you have designated. But the site has removed one non-profit from its program: The Alliance Defending Freedom.
As The Federalist notes, the SPLC, a leftwing group that has inspired several mass shooters, has listed ADF as a "hate group" because ADF helps Christians around the country who have been targeted for harassment. One of those Christians, Jack Phillips, has a case pending before the Supreme Court right now.
The SPLC objection is that ADF helps Christians, which the SPLC and now Amazon.com has concluded means the ADF is a group of bigots fostering bigotry.
This is bigotry in itself and it is unfortunate to see Amazon engaging in bigotry against Christians.
