the pro gun lobby always seems very vocal on this site. I don't know if that resembles how it is in America itself.

I think perhaps Michael Moore is saying it for a lot of people who feel unease at the present situation and don't want to face the browbeating and ridicule, anybody who sticks their head over the parapet on this site does.

I can only surmise that might be the case, as the subject is a wee bit less than fascinating for the rest of us who aren't directly involved.
