Social networks are not and have never been neutral carriers, nor are they required to be such. They have always been "arbiters of truth and morality" in that they have always blocked certain kinds of content, like threats and CSAM. Few if any legal platforms have ever allowed the live streaming of a murder.
The new nazi's reign of global terror and indoctrination is just getting started.
Be prepared for these extremists and terrorists to grow bolder and bolder. They consistently equate empathy with weakness; the leading Nuremberg psychologist concluded "Evil, I think, is the Absence of Empathy" [0].
Are you for leaving ISIS beheadings up on social platforms as well? Those are "legal" in the jurisdiction where they happened (self-proclaimed caliphate and all that).
What about CSAM from countries with lax laws about those things?
Your comment about LBTQ+ is interesting. That is most likely blocked in backwards countries where things like that are illegal, or various platforms would face consequences in those jurisdictions.
