Suspended from Twitter over the Civil War

Elon finally dropped the ban-hammer on me when my free speech was too much for him to bear. 

During a discussion about the Civil War, Becca Pentland said "They should have been dealt with after the Civil War!".

I replied, "Yes, if the USA would have just hung all the rebel traitor leaders, we wouldn't be in this mess. We should have executed all the confederate heads of state, their traitor president, their traitor generals."

Talking about what the US Government should have done with traitors one hundred and fifty years ago was too much. For this Twitter suspended me.

I appealed, with this:

"Suspended for talking about how USA 150 years ago should have hung the Confederate leaders and generals, to avoid the current situation. It is legal punishment to execute traitors, especially during the Civil War 150 years ago.  Clearly this is not inciting, threatening, glorifying, or expressing a desire for harm or violence. I was talking about an event 150 years ago."

Nevertheless, Twitter found that discussing a 150 year old war violated Twitter TOS. 

It's one thing to be transphobe, a nazi, a white supremacist, a misogynist on Twitter. For Elon Musk, these people are acceptable, as is their content. But if I critically talk about the history of race relations and theory in the USA, Elon Musk kicks me out.
