Personally, I am agnostic. I do not go to any church.

The following seems rather irrational though.

1. Gather lots of people together, who share a religion.
2. Make the gathering open to the public.
3. Gather regularly, and predictably.
4. Recognize, due to prior events, that other people want to kill members of your religion.
5. Allow your congregation to be defenseless.

Seriously. Leftists say they believe in science and logic, but where is the logic in allowing murderous individuals to kill your family, friends, neighbors, and fellow worshippers when you know damn well that the sick bastards are, in fact, ready, willing, and able to do just that.
