Twitter's censors, however, do not honestly state what they are doing. They do not say that they are trying to abolish all negative thoughts and attitudes toward Blacks. Instead they falsely characterize a mere statement of fact or opinion, if it happens to be unflattering to Blacks, as harassing, threatening, or promoting violence.
A mere statement of fact, if it happens to be unflattering to the Negro race, is deemed by Twitter's small-brained censors to be a call for violence.
In the aftermath of the Pittsburgh synagogue-shooting, it seems that Twitter has decided that disputing the Holocaust is no longer acceptable, probably based on the same premise, that criticizing a group is the same as advocating violence against that group. This logic comes from Deborah Lipstadt: if you defend the Germans, you are really attacking the Jews, because defending the Germans involves calling some Jews liars. If this attitude is accepted, the net effect is that Germans and White people in general are obliged to accept abuse without responding.
It is certainly true that accusations can lead to violence. The Holocaust itself is an old piece of war-propaganda that is resurrected whenever a new war is to be justified. Unapproved leader X gasses his own people! Unapproved leader X must be destroyed!
Similarly, the completely unfounded inflammatory propaganda that mass-media aired following the Trayvon Martin incident, and also after the shooting of Michael Brown by Officer Darren Wilson in Ferguson, Missouri, caused incidents of violence against White people and police. (I go into some detail about that here.) But there was no movement saying that criticisms of White people and police must stop. At least, I have not heard about it, and Twitter is clearly not influenced by any such movement.
I wonder when Twitter will decide that criticizing President Trump is the same as advocating violence against President Trump. I won't hold my breath waiting for that.
