Earlier quoted context omitted.
That's actually the logical conclusion of "no tolerance for intolerance". Actual intolerance will re-emerge while using that as a slogan. I honestly don't see any other conclusion while divisive identity politics is the culture. Every election and debate is just subtext for making sure your people are in power to protect your people.
It's a paradox. The point is that tolerance cannot be limitless. That doesn't mean that intolerance won't prevail, it just means that those who strive for tolerance need not achieve perfection. There will forever be a balance to be struck, and it's natural to have disagreements about it.
I think the thing to strive for is a more perfect due process. I'm concerned people are instead looking for a more perfect way to label and shun transgressors. And they use hate and fear of intolerance as a key justification.
So how do we stop that? Or, rather, why haven't we had any luck so far?
