An app called Bless Every Home, which has been backed by some of the biggest names in evangelical circles, is mapping the names and addresses of immigrants and non-Christians.
Maybe not the best idea. According to the article, using this app they can leave notes about you for other members to see. Talking about satanism would probably flag you for even more harassment.
I do that all the time. I don't care if you're a christian, Muslim, Jehovah's witness or whatever else, if you come to my house uninvited to tell me why I should follow any religion, be ready for a heated debate on why that's not your place, I dont care what your leaders have made you believe. Its one thing to talk about Christ to tell anyone about Him, and then drop it and move on to a civil interaction, its an entirely different thing to splat your believes on people's faces and telling people they will go to hell if they don'tdo what you tell them.
We have friends of all religions and lack of religion, and we have never attempted to change them. They know what we believe in, we know what they believe in, and none of that makes any difference.
I'm glad I dont live in the US, nothing more disgusting than mixing faith with politics.
