Those items you listed would fall under my definition of "politics".... but that's just me.

You will get to know other members to a degree slightly less than if you discussed politics and religion. Surely you can get to know members' interests and opinions outside the hobby by asking questions that are not political or religious in nature.

For instance:

Ford v.s. Chevy

Cabernet v.s. Chardonney

Stros v.s. Sox

Fish or steak.

I'm sure you get the idea.
