It's such a weird feeling. My parents church I grew up in does alot of good things - resettling refugee families, raising money with 5k runs for a family that had lost a father in Iraq, or giving gardening classes, etc. And I still like christmas. I like when a sermon makes people squirm for our absolute obsession with wealth. So yes, I can visit and feel my own huge hypocrisy, sitting in the pew believing that no deity has ever existed.
Edit - churches should also be raising money for Iraqi families that lost fathers to U.S. bullets.
