and come as you are - that has been the message of our movement. Not exclusive 'us' but inclusive 'us' - everybody is welcome. Every body, but not every person, corporate persons are persons we would rather get rid of.
This movement is not about people against people, us against them, Christians against atheists or atheists against Christians or any group of humans against each other. Only 'them' we really oppose, in the name of humanity and future of our children, are corporate persons, hierarchically organized greed and rule of Mammon.
Singling out Christians and refusing their support and discouradging their participation would be against the core principles of our movement, yours and mine. I trust that you wouldn't like your attitude being interpreted that way.
