I don't think the use of a word like 'fight' should be treated differently for powerful figures/politicians - it feels a bit arbitrary. Why not treat Facebook or Twitter as a platform that in aggregate has that degree of influence and power, and ban all uses of the word 'fight' across the entire platform? Think of it like what Apple did when banning the 'pistol' emoji across all their operating systems. Why does it matter whether one politician does it or if ten thousand activists do it - after all, in 2020 the latter group incited a lot more violence than Trump is alleged to have incited.
My perspective is that these efforts to ban speech or speech that includes "human emotion" (like 'fight') would be a step too far for everyone. Right now those rules are being applied to only one side (the right), and so others (on the left) are deeming this censorship acceptable. This is quite evident if you look for all the instances when Democrats used the word 'fight' (https://nypost.com/2021/02/12/trump-team-plays-videos-of-dem...).
> a certain percentage of people may very well misinterpret that as a call to violence
But this is why our society is built around individual, personal responsibility. Those that follow a call to violence are still, solely, responsible for their actions. Our justice system charges those individuals that engaged in criminality on Jan 6th, not Trump. Why should these massive tech platforms be any different in determining who they censor or ban?
