Like a lot of bigots they will attack you online but haven't the courage to do so to your face.
I realize I haven't been around much lately (when you're busy, FR is one of the first things to go), but I have news for you - they will attack you and what you believe to your face. People who have fallen away from the church for strictly human reasons are the worst about it, too. They blame the Church for their unhappiness, when they haven't invested much in it at all.
It's really rather sad.
