I think you are not getting an accurate picture of the average OCer. Keep in mind that MEM is an extreme example of someone who OCs and is not able to get a CHP should he wish to. Many OCers do in fact have CHPs. I've hadCHPs going back more than 18 years, before Gov Foster signed Statewide CHPs into law.
A few, like yourself are too young to apply for a CHP and others could get one but have decided that the hoopsthey have to jump through to get one just aren't worth it to them.
There's no big deal, not much distainand I think the more you learn about Open Carry the more you will learn that things are not nearly as polarized as they seem at first.
