Right - What Northam is really afraid of is thousands of Virginians chanting "We will not comply!". He's just trying to discourage resistance to his edicts.
It's a vicious circle. Virginia Democrats think gun owners are dangerous. So they pass laws to make them felons. Virginia gun owners may show up with their guns to protest. Virginia Democrats will say, "SEE! They're dangerous!"
Of course, now if they don't show up to protest, Virginia Democrats will proclaim that the gun ban in the capitol on 1/20 was effective, so therefore gun restrictions are effective.
