When there's a lot of chaos in society, it's useful that your faction has the most guns.
Lefties go "constitution is outdated, you can't beat tanks with rifles, therefore having guns is useless". Reality isn't that black and white tho. If your faction has the most guns you might not even have to use them.
I don't know who you mean by "lefties," but I don't hear anybody staking their ideology on "the Constitution is outdated." Except, notably, the orange RINO-in-chief.
