I'm not here to overgeneralize:
I say just let them do whatever they want. Charity can be given to anyone of their choice. If they want to look like asses for not giving because of XYZ reasons, then let them look like asses. But when people wonder why their religious group is declining, or there is a lack of them in the future..... well just look at the factors that deterred people.
Everyone needs to play Lost Odyssey! Any opposition to this and I will have to just say, "If it's a fight you want, you got it!"
