Hell yeah on the Religious stuff. I consider myself Christian, but I stay well away from even talking religion when I possibly can. If you just look a the last couple of thousand years, there are few better ways to get killed than religion. More recently, there are few better ways to get on someone's bad side than to discuss religion...Yep. It works both ways. Stay out of religion also.
We took our first child to the pediatrician in 05. He started off with a Jesus juke. I stopped him right there in mid sentence and said. "If you take excellent care of my child you may in time earn the right to go all John Piper on us."
