The purpose of suggesting that "extremism" as a term is "so vague as to be meaningless" is to imply precisely that. It's a common enough rhetorical tactic that it can be taken for granted in any thread where speech or censorship (particularly of what is considered right or far-right politics) is the subject.
Extremism in context has a commonly understood definition, and claiming otherwise is not a convincing argument.
No, parent pointed out what I repeated, that history shows that freedoms are lost incrementally. You are the only one talking about inevitability.... which is par considering you also think it's totally obvious what some word that by it's very nature is inherently undefined, means.
My point was not that ‘extremism’ does not have a definition; my point was that what content falls under that definition is very much subjective. I could have phrased my original comment better.
Obviously, the drafters of this agreement had certain types of content in mind. But those people are not the ones who will be implementing the policy.
The types of content targeted by this kind of policy depend very much on who is making the decisions.
But that may be too subtle a distinction for a thread like this.
