I grew up in NYC and lived there for most of my life. I am used to, and prefer, a diverse human experience.
Ham radio, on the other hand, once again, in my personal experience over the ten years I have been licensed; is not diverse. Not nearly as much as it should be.
And, btw, my on the air experience is that I know almost all of the folks that are on the various repeaters, either because of my ARES participation, or club participation. So I have met them in person. It's not a case where I am assuming that because they "sound" a certain way that they are a certain race or ethnicity, I don't play games like that.
So, my personal experience, both in NYC, here in Cape Cod where I live now and reading the ham rags over more than thirty years is that ham radio is overwhelmingly a white, male, middle-aged hobby.
It shouldn't be that way, is my point.
Do I care who I'm talking to other than that observation? No, of course not. When I'm on the air or at a meeting, or working an event, I am there to have fun and play radio.
The OP, seems to me, has made an observation and is wondering why there is this aspect of the hobby. He is not enunciating a preference.
Or, he's a troll trying to get an argument going, but so far I don't think that's the case.
