You don't seem to acknowledge a critical difference between where we are and where they are.
It is legal for you and I to OC normally, with handguns, without a license, in Nevada.
Rifles or black powder are the ONLY legal way for them to carry without a license.
Yes, it has problems. Blame the Texas legislature for forcing them to do it that way, before blaming them for the attention it causes.
You are telling them they should be UNARMED instead of carrying a long gun, unless they go black powder.
BTW: There are no "open carry rules" in Nevada. It is not addressed. And half-concealment and "printing" is also usually a bad idea, in my opinion. Poor concealment, when you are concealing, alarms sheeple, too, whereas purposely openly carrying does not.
