Almost literally every person is "in favour of limits on speech" to some extent, so this kind of reductionism contributes nothing (and I'd argue generally makes the signal-to-noise ratio even worse).

There are huge numbers of interesting questions around how we treat freedom of speech in a civilised society. What restrictions can we collectively accept? How do we ensure that individual rights to speech are protected? How do we protect people from harassment or abuse, and how does this balance against the fundamental right to be offensive? Discussion about these is way more interesting than hot takes about how we're all going to prison for being mean on Twitter. And worst of all it detracts from the serious conversation to be had about how grossly inappropriate the reaction in this specific case is.
