My reading of that is that some such advocacy is "across the line". Which is which, is a purely practical judgment. A youtube rando with no IRL power would not concern Popper no matter what she said, while someone like Hitler leading a party of fascists obviously would even if he spoke mostly in dog whistles. Drawing the line requires judgment, not an attitude of "it is society's right to crush those it deems intolerant and society will always exercise that right especially if it makes a military contractor a bit more profit". As we see ITT, Popper was wrong, because authoritarians will often demand that the state exercise such "rights" to the fullest extent. I think maybe Libya war cheerleaders like B-HL must not have read that last sentence in the quote too carefully.
