I don't do it but it doesn't bother me.
How does one "abuse" a right?
Exactly. The only reason that people become nervous around someone with a firearm is because it's not a social norm. I'll be honest, if I see someone open carrying and they look clean cut and carry themselves with intelligence it never gives me the slightest concern, in fact I like seeing people carry because I know that statistically they are a good person and can address a threat if needed.
On the flipside if I see someone wearing baggy clothing, dressed like a thug, carrying themselves like a threat then the thought "are they packing" is always on my mind and I stay situationally alert.
I see no problem with sidearms and while I prefer not to see it because it scares people, I support open carry of long arms as well.
Is a right really a right if you can't exercise it?
I personally will only open carry while outdoors and would prefer to go unknown in public so that I'm not seen as a threat and have the greatest likelihood of stopping a threat unscathed.
