> "... unless it's speech we disagree with"

That isn't the standard. The OP addresses an unavoidable, fundamental paradox of freedom: Someone can use their freedom to limit the freedoms of others - if we support that person's freedom, are we supporting freedom or oppression? Are we free to oppress others?

The philosopher Karl Popper famously addressed this issue. Here are a couple more ways to think about it:

* Freedom as a social contract: I support your freedom and you support mine. If I support yours and you take away mine, you've violated the contract and it's void.

* In a society built on freedom, those who use their freedom to take away others' freedom are parasites on society.

Arguably, the only speech not to tolerate is intolerance.

But that's all philosophy. Practically, nobody believes any freedom is absolute. Freedom of speech is revered and in the first amendement in the US Constitution, but nobody thinks it's absolute: you can't slander people, defraud them, threaten them, create dangerous situations (famously, you can't yell 'fire' in a crowded theater), etc.

>create dangerous situations (famously, you can't yell 'fire' in a crowded theater), etc.

Every time someone brings this up, I feel obligated to mention:

1. The phrase came from a supreme court case that ruled an anti-war activist's leaflets were illegal, because it was promoting people to dodge the draft. I doubt many people arguing for free speech restrictions would support this case, even if they agree with the principle.

2. Practically speaking it's no longer relevant because it was overturned with "imminent lawless action"
