Sounds like extortion to me. Seriously guys? You are going to tell a charity "I'll donate but only if you take it in bitcoin"? What a shitty way to deal with charities. Is this really how you want people to view this community?
Not extortion. Charity X will simply be approached with at least 100 BTC in hand, and kindly requesting them to consider accepting Bitcoin as a donation option. It's not like we'll be telling them to do such and such or else no money from our group.
I respect BadBear's opinion, but would someone else here be so kind as to express my sentiment more clearly. I feel my above statement doesn't do it justice.
