Calm down gloria you sound real intelligent on the subject and obviously know more than I care to about "Terminal bullshitistics"
and all but this web site is intended for people to discuss their opinions which I have done, if you disagree thats fine.
An opinion should be based on something beyond personal perceptions and wishful thinking. "A .22 if fine" is based on nothing and incorrect just as "creatine causes brain cancer" would also be an opinion based on nothing but subjective feeling.
Me, I base my opinions on something beyond subjective feelings and I tend to listen to those who clearly know more than I do on a topic.
And by the way if 2 thugs come at me with the intentions of harming me and I have a .22 they will die,
False, and again, based on ignorance of the topic and wishful thinking on your part. It's also irrelevant. A .22 will kill a person. That's not the issue. Many people are shot with a .22 don't even know they have been shot, and bleed out some time later, often after beating the person to death with their own gun, but I digress. The issue is the speed incapacitation of an attacker, not whether they die or not. I see you are all to happy to pretend you have any knowledge of this topic, and will cling to your perceptions, which appear to be based on watching too many movies and video games or something.
hell if I have a knife they'd have a bad day. The point of conceal/carry is to dissuade people who want to harm you to leave YOU alone, and any firearm will do the job.
Also false. The point of CCW is to have a means of self defense if your life is in danger, not to wave a gun around and hope it dissuades your attacker. In most cases, showing a weapon will in fact stop the attack, but if "any gun will do" then you might as well carry a fake gun. Bottom line is, you hope for the best, prepare for the worst, and CCW something that is a recommended SD gun and round by those who actually know something about the topic.
Now if you want to kill someone for the sake of killing and make sure they're dead buy a .40.
False. So much ignorance in a single post. Congrats.

Now, if you would actually like to understand the topic - and I have a feeling you really don't - probably the most accurate reading on the topic is Handgun Wounding Factors and Effectiveness from the FBI found here:
http://www.firearmstactical.com/hwfe.htmThat is a the "must read" document for anyone wishing to get a handle on the topic of terminal ballistics for the non science reader. The Wiki page on "stopping power" does an OK job of covering the issue:
