So, while I can't agree with most of what you wrote, it is interesting. A few quick issues, if you don't mind.
Did you link to a tv show? What does that illustrate?
Do you really clip your gun to your underwear? Your underwear must be pretty beefy.
Capacity is a good thing, though no one will call me capacity obsessed. I personally would rather have 5 rounds of .38 than 8 (possible) rounds of .22
Failures of .22 in civilian hands is not something I can quote off the top of my head. I will say that I've seen people get shot with .22's out of a rifle, and dealt with others who had been shot with .22's out of a pistol, and none of them were particularly inconvenienced by the hits. Months later, one had long term hip problems that make her limp a bit, but not much at the time.
As far as Walt and John's quotes, that's great for dabblers (in the context of your post. I doubt it/they were meant it to encourage people to carry .22's) For those of us who spend more time training than on the internet, we can have caliber and competence. On the other hand, if John is talking about 9mm vs. .45,(which I suspect, knowing John) I might be able to get on board with that, since an awful lot of noobs think they can buy competence in the form of a .45 1911.
A complete aside, what kind of accuracy do you get out of your gun/ammo at 25 yards? I'm still looking for a good pocket field gun in .22.
