I didn't thank anyone simply because I am not nor would I want to be part of it, even if I were a Christian. I hope the originator deleted those post because it was the right thing to do & not because she could have been banned from Facebook for allowing it.
I didn't join the facebook page. Actually, I didn't even know about the facebook page until it came up here. I guess the Christians on my friends' list were thankfully not involved in anything in direct opposition of Christ's teachings. I think(?) if they joined, "liked" or commented there that it would show up on my wall, but facebook keeps changing things so often, who knows?
of course you didn't join the FB page you are an atheist.
