Yep, an interesting idea, and definitely something worth thinking about and discussing.
The problem is that people like the GC pretend that this is some sort of Universal Law which has been proved to be true, and therefore use it as a carte blanche to "weed out intolerance".
Unfortunately it is not a such. It's just an idea, unproven and untested.
Though it's also worth noting that I highly doubt Karl Popper would've agreed (based on his various clarifications) with almost any situation where it has been used to justify silencing "the intolerant" on the internet in the last decade.
