OP said "The idea of the host (who was prejudice against OP's wife) receiving my money was galling".

OP wasn't complaining about the discrimination, he was complaining about _doing business with the person who discriminated_.

Wildly different things.

Laws (or rules) don't exist in a vacuum, and blindly following them is dumb. If a company rolls out a bad rule, you can either follow it, ignore it, or try to change it.

Just because it exists means nothing.
