Open carry is the least of their problems right now.
I personally am a concealed carry guy, but I do understand the open carry crowd. In my mind it’s a push back against the whole “guns are icky” campaign being foisted on our kids. My kids know better, as do my grandkids. But until and unless we get the general public to look at an open carried firearm no differently than an openly carried cell phone, we still have work to do.
