@DashEquals @sjw Opinions can certainly imply actions, the line can be fuzzy.
Saying someone doesn't deserve to live isn't quite the same as proposing the action of stopping them from living; it depends on what you mean. But while it's still an idea, it's just an idea. It doesn't even have to be a sincere idea. If you've ever read A Modest Proposal, the author advocates eating Irish babies. Swift was clearly not serious, it was intended to satirize the English treatment of Ireland, but if you've got a rule that says you can't say that sort of thing, into the gulag he goes, he literally said people should eat babies based on their race.
If someone holds the belief that all X should be rounded up and shot, how did they come to hold that opinion and what stops them? If they can't talk about the idea, they've only got one side of it.
And there's also a difference between someone saying "All X should be put onto boats full of dynamite" as a regular person who cannot possibly carry it out and as a dictator that has the capability to order it directly. If the prosecutor says you're guilty, that's different from the foreman of the jury announcing your verdict of guilty. One of those is an opinion (which may not even be sincere but which is the prosecutor's job to say) and one of those gets you declared guilty by the judge and a sentencing hearing scheduled.
So I think it's fine to advocate for anything. If it'd get Jonathan Swift gulag'd, I don't want it. If it allows the government broad leeway to decide what someone's allowed to say, I don't want it.
