I don't think that you pulling a gun on him stopped him attacking you

I don't think he said he pulled a gun on him, but rather just made the gun visible.

Having a gun in your hands just allows you to make life/death choices against other people - I don't want to *ever* be in a situtation where I can choose, or not, the life or death of another human.

Yeah, you just place that burden on a few brave people who work for the police. This is the same sort of hypocrasy with people who condemn hunting because of animal cruelty then they goto the supermarket to buy some fresh meat. You just don't want to get your hands dirty.

And by the way, I won't be making the life or death choice if someone breaks into my house. The thief will make that choice for himself.
