First I call BS on the whole story it sounds made up, but just so I understand this correctly, YOU willingly engaged with someone who's opinions are different than yours. Verbally harassed this person, again because his opinions are different than yours and the only reason why you did it is because you felt like a big mad with YOUR gun, we have no idea if he had one or not. And the person who did not start this altercation or do anything after you did your little song and dance is a "DIPSH IT" AND A "Knuckledragger"
You are right they do reduce a persons inhibitions, why didn't you challenge him to a fist fight if you are so brave or are you only brave when you have a gun?
