Several times in my life I've encountered people who seem compelled to tell me "you're nothing".
Which is interesting, since I don't remember claiming to be "something" more than what I am- which is me. Whatever others may decide to call me is their business. You may or may not like me, but that's just how it is.
Years ago in the town where I was commonly known as "The mountainman" (or "the pet store guy", depending on who was talking to/about me) I encountered a drunk who insisted on telling me I didn't measure up. His little toe was more of a mountainman than I could ever be. He kept getting right in my face to tell me exactly what he thought of me- which, since I had never met the guy, really wasn't that important to me. His little yappy long-haired lapdog was a "real mountain dog" according to Mr. VaporBreath. I just kept saying "OK. If you say so." (As an aside, this is one of the few times I ever pulled out a gun in preparation to use in self defense- although he wasn't aware I had done so. I was almost certain he was going to attack any moment as he got angrier and angrier- but he suddenly calmed down and left.)
Online I have had people tell me I am not a "real libertarian" or "real anarchist" because I'm not shooting bullies, or sitting in jail. Or moving to Somalia.
It seems that whatever I get a reputation for, someone is just waiting to try to tell me I'm "nothing".
And, I used to care a little, but less and less all the time.
I've never claimed to be perfect. I don't suggest you follow me. I'll tell you what I think I should be doing- maybe I'll measure up... maybe I won't. But I know where I should be. And, yes, I'll probably judge your actions according to what I think is right. But why concern yourself over my approval?
You'll probably not get me into much of a battle trying to convince you I am what you say I'm not. Instead, I'll just go out there and be myself. I'll let my actions speak for me- and either prove you right or wrong.
