From a statement issued by the fundraisers:
We want to thank everyone who has supported Camp Quest Oklahoma this week after their fundraising event at a barbecue restaurant was cancelled on Monday night. The cancellation of their fundraiser, which had already started, was due to the restaurant owner, Joe Davidson, claiming that supporting the camp wasn't compatible with his Christian identity. Since the cancellation, Camp Quest Oklahoma has raised over $5,000 in donations, and these donations have come from Christians as well as members of the secular community. We know that Mr. Davidson's views and actions do not represent all Christians, and have been especially heartened to see messages and donations from Christians like one man on facebook who said "I am Christian and read on Reddit what happened. Donated because what they did was ridiculous. Hope it helps."
It was nice of them to include the part I bolded.
