That said, his point seems to be that FB is banning e.g. Farrakhan without making any effort at disproving Farrakhan's claims, and furthermore that many of the commenters in this thread are similarly dismissive of Farrakhan's claims without offering anything resembling a good-faith disproof of those claims.
(Note that the parent and I are not making any statement about Farrakhan's correctness or incorrectness, but are instead merely noting the widespread absence of proofs about this correctness).
Personally I know essentially nothing about Farrakhan and his claims, but I like to believe that I can think critically enough to evaluate his claims on their merits, and do not need to be "protected" from hearing them by Facebook or anyone else. I (and perhaps the parent poster) would like to participate in an agora of ideas where everyone is welcome to promulgate his claims, no matter how allegedly outlandish, and the strongest ideas will win on their merits. Contrast this to a situation wherein the winning ideas win because their rivals are excluded from the agora.
Of course I don't mean this just about Farrakhan. Similarly, I have never read the Protocols of Zion, which are mentioned several times elsewhere in this thread, and I have no clue whether they are related to a Jewish conspiracy for world domination etc. But many commenters here are asserting claims about the Protocols, without offering any attempt at a proof beyond a link to Wikipedia, which personally I find very unconvincing as a matter of principle, on this and any other topic.
In general I am not convinced by assertions/bannings, and prefer evidence.
I said:
1) At some point, if you allow a view to be expressed on your platform, you become somewhat implicated in that view spreading.
2) I believe (and I think FB believes) that the views these people promote are harmeful.
Now, should we trust Facebook? No! Facebook has banned many people and groups for far less than these people were banned. The reason Facebook is pushing this news so hard is that they have been letting things slide again and again because these people were prominent figures (see also how Twitter keeps not banning trump despite his many threats of violence).
