Do places even have the slightest clue that "a portion of all purchases goes to Christian charities" is not a universally good thing? I was just doing some online clothes shopping. I clicked a link, and the site's main page had a big announcement in their rotating banner saying that very thing. I didn't even bother to look at the clothes. Buh-bye. Frankly, I would prefer that any charity money coming from me would go to actually helping people, rather than handing out Bibles or communion wafers.
Do they think Muslims and Jews want to be supporting their Christian charities? Really?
