I haven't seen too many of his videos, but he does have an interesting perspective; especially if trying to "stereotype" based on his appearance.
I'm tempted to disagree with him, but then realized my exposure to the "gun culture" is pretty limited. The individuals I know when firearms don't act like they add masculinity, but I only see a very small subset of that "culture".
I do think notions like honor, compassion, discipline and responsibility aren't as valued today. My favorite sound bite from the video was "If we had self-control we wouldn't be talking about gun control".
Anyway, interesting perspective, thanks for sharing it.
