I typically carry X many forms of photo ID; X =

Assuming he lives in the united states is not enough. It is not legal in all 50 states to carry a concealed weapon

It's a reasonable assumption though. There is only one state (Illinois) in the US which completely outlaws concealed carry. The other 49 states all have some variation of concealed carry law in place. I'll grant that in places like California, New York or Hawaii it's difficult to obtain one unless you're wealthy or have the right friends, but many of us live in more enlightened states with "shall-issue" laws in effect.

As for businesses and schools, you simply have to be aware of the laws of your state and behave accordingly. I don't carry on school property and I've stopped doing business with companies which choose to disallow carrying on their premises. It's really not that complicated.

Here in Britain the only photo ID I have is my driving licence and my passport, and I never carry either, to avoid losing them.

The only time I was pulled over by the police I was given a "producer" - 24 hrs to show my licence at a police station; my passport is only for going on holiday.

I suppose that's why government talk of ID cards causes such debate over here.

I can think of a few more reasons why it's BS:
1) it assumes that there is such a thing as universal evil. The real world is not so black and white. It's not even shades of grey.
2) it shows an utter unwillingness to see things from another perspective. (My evil is not your evil)
3) It's a bully statement. Negotiation is not domination.
4) It induces a weapons race (communists are evil!)
