When we know a person is a Freethinker and they sneeze, we asked them if they are okay? Why? Because when you sneeze, your heart stops. If you are okay then we can continue life, if one does not respond or says no, emergency action is required. That is the “logical” thing to do!
We respond in a different manner to theists friends/family that do not know our non-theist position. Some members don’t say anything.
