Completely agree.Don't let these caliber clowns dissuade you from smaller calibers. They'll still kill a full grown man dead as shit if they hit the CNS and follow up shots are a lot easier if you are using a caliber you can control the recoil on.
The only issue I have recommending a 22LR (if there are other options) is because .22LR's (in semi's) are more prone to misfires than centerfire cartridges.
A .22LR revolver - just squeeze the trigger again.
A semi auto .22LR -- the shooter better know how to tap/rack and clear jams.
