Hey, carry what you want.
It IS a fact that some DO carry large evil looking knives. It's when a few juvenile minded users "whip them out" and make an aggressive display of using them that creates an incident. On the other hand, others apparently go out of their way to make it an issue even when said knife has never been seen by them. I was called out for wearing a Buck in the office, a folding hunter in the black cordura case. They wouldn't have known it except for the gold embroidered lettering.
We get it on both ends - boys who are showing off their enhanced masculinity, and "others" - not always gender based - who will seize the moment to make their political statement of the day. I swear there is a secret paper of talking points that outlines how to do it.
Since most of us are trained to be polite in public, I see and read the common reaction to someone making a scene over a knife to largely back off and avoid further escalation. That's good. It means we aren't going to extend the confrontation with explanations or worse, put downs.
What I DO see is that said confrontations when posted about have a profile of both participants. If the knife user is a young male, and the knife is anything but traditional, he gets outed. The person making the comment is usually liberal, often female, and usually over 40. The situation is that they see the user as someone they need to put into a subservient social position. THAT'S what is going on - it's social warfare, guys, not knife hating. The knife is just a useful excuse. What else are they going to complain about, your boxers? Well, maybe if that's all that is covering your butt.
I'm almost 60, got that touch of gray the men's hair color sellers are trying to market, and I get more comments on my watch than my knives. Most I use are tacticool - but small. I quit toting 4" folders because they are 4" - big isn't what I need daily. But I have been carrying a BM Vex, or CHB Bokers, a Ti M16, and lately, a spearpoint Boker Magnum Tech with cf scales. Hardly traditional, and nobody says anything.
It's the younger user who gets the crap thrown at them, I DO see that happen in retail all the time. American society goes out of their way to put down young men to put them in their place. Whether or not we need to, there is a mindset that young men have to be monitored and kept on a verbal leash so they don't get out of line.
Wonder why?, like I don't know. Was one. People have a few difficult experiences, and from then on, they continue to react when they perceive the same circumstances. Like a vet diving for cover hearing a loud noise, they engage in a behavior designed to protect themself. They ARE afraid. We learn to modify our behavior. Life goes on.
Except for those b's that look to put someone down. They aren't going away, and they like making a scene. For them, I am still looking for that comeback.
