Since I know some liberal gun owners, I can tell you for a fact that your generalization of them as being overly emotional and violent simply doesn't hold water. I know some liberal gun owners, who happen to have a very hard time admitting to folks they are liberal gun owners because of the backlash that comes from that admission, that are just as responsible, just as well trained and every bit as enthusiastic about guns and gun ownership. They have admitted to being ignored by their own party, but since most are not willing to be single issue voters, supporting their party for many other things that are important to them, while silently enjoying the rights their own party seek to restrict, knowing their own party is working against them. As a former member of the Republican Party (now non-affiliated) I can say I've felt that way about my party in the past.
Honestly, I know folks on the right that I would rather not see with guns in their hands. Party affiliation isn't a great determiner of whether someone is stable, intelligent, rational or reasonable. We tend to reduce it to that, but it's far to great a generalization, and in reality, only applies to a portion of the whole. Again, that applies to both major party adherents.
Yes, there are those on YouTube who make responsible gun owners cringe at their unsafe, moronic escapades with loaded weapons! Makes this former Marine PMI want to 'counsel' them in a most personal manner!
