>When the {Sacred Value} is participation in the marketplace of ideas, then guarding it against unwelcome elements is the same as destroying it. When your justification can be used, identically, word for word, by the same people who believe the opposite of your beliefs, then it's not a logical reason, but a justification.

My "justification" is not usable identically, word for word, by the same people who believe the opposite of my beliefs, because they do not believe my beliefs. I, and you, and anyone else, can establish this by reading the cited links in my post above. Further, the {Sacred Value} under discussion isn't "participation in the marketplace of ideas", it's tolerance!

Society does value "participation in the marketplace of ideas", but that's another can of worms; not entirely orthogonal to tolerance, but it's obviously not the same. In fact, I'd suggest that overreliance on the "marketplace of ideas", which, like any marketplace, is most easily dominated by those with the most money, is exacerbating society's problems with tolerance.

>Regarding the examples of criminal action, I'd heard of some of those events. I've also heard of

All the examples you cite (a CNN host, individuals talking about physically opposing self-identified Nazis, "comedians jailed for jokes", teenagers jailed for singing) are individuals. They may be being oppressed, in your view, by monolithic forces of intolerance, but they themselves are not monoliths baldly angling to protect in-groups which the law does not bind, alongside the exclusion of out-groups whom the law binds but does not protect. Speaking of which--

>Giving one group the right to cancel the civil liberties of the other group

But that's not what's happening. One group is cancelling the civil liberties of another, visibly, but they are keeping those rights for themselves. When the Black Panthers armed themselves, Reagan, of all people, instituted gun control, and now LGBTQetc groups protecting LGBTQetc events get called out by those who were previously using those same arms to threaten them; curtailing access to abortion is a great good, but "the only moral abortion is my abortion", and so those with means get 'em anyway from elsewhere.

>It all reduces down to that Orwell quote, doesn't it?

Yes, some animals are more equal than others. That's what I'm saying. Rules are for the little people, not the important people. The important people can break the law and act immorally, and it's our fault for not stopping them. That's Murc's law. Popper's political solution only actually works if there are actual checks and balances, but most of them seem to be legally toothless and highly dependent on the moral standard of the individuals involved. It's my understanding, for instance, that every President since Nixon has voluntarily released their tax returns in order to promote trust; Nixon didn't for eerily similar reasons to those bandied about in modernity.

>I'm insulated from most of this, I realize, by not being American and not having the same intense loyalty to your political tribes

I'm not American. I assumed you were, by the examples of left-wing badness largely drawn from talking-head American media, and certain nuances of your defence of the political right. I don't like the American uniparty, but the simple fact is that one wing of it acts very differently than the other. They seem to functionally agree on like 75% of things (big military budgets, pro-Israel, the 1/5 of the GDP provided by for-profit medical care), but the wedge issues have become meaningful socially, and are being exported abroad. We all benefit from, and are all bound by, the Pax Americana.
