The beautifully controversial world of guns

Has it ever occured to you how values differ between gun wielders and un-gunned people?

The first of both would see the above advertisement as completely natural as they would any Kellog's or Wal-Mart ad. The latter would rather view this opinion as obviously right as the fact that they are alive.

What makes people of the the same continent, or even country, have so different values on such a sensible matter? Is it education? Growth environment? Is it just something some people are born with?

I have no answers; only a damn good question.
