The left is really not interested in "equal treatment". Just look at affirmative action.
I have looked at affirmative action. I've also looked at people I know personally who refuse to allow blacks to work in their departments, even though the blacks are more qualified and have better references than some of the white guys they hire, and despite the job being in a public facility, not a private one. Affirmative Action was the equal and opposite reaction to blatant anti-black, anti-woman, anti-native American, anti-minority discrimination in hiring. There's at least one facility a few miles down the road from me that could use a good strong dose of it right now.
Affirmative Action has it's flaws, the biggest one being that two wrongs don't make a right, so an utterly simplistic tit-for-tat gets us nowhere, but it was better than allowing egregious bigotry and arrant nonsense to continue to undermine our economy and our society.
Anyway, I think you underestimate the Left's appetite for Just Desserts with Gander Sauce. If the Right wants to pitch their tents on top of Mount Second Amendment, the Left will be happy to send their envoys, the HPNGC, to join them there, openly carrying, with ammo and armor for
all.
