@artemus_5 sometimes history needs revising. The first version of history is always written by the powerful and the victorius in a given conflict. The first version is rarely much more accurate than the first revision. Its a free and unfettered press that usually helps humanity see the truth, even if they choose to look away. A couple of recent examples you mention like Kristallnacht and the Armenian genocide were perpetuated by the far right who despised liberal principles. Thankfully the truth came out because survivors escaped and a free press reported it. Other recent examples:the Gulf of Tonken and WMD.
I havent seen Hamilton although I understand it is a well done event. I also believe that an American has a right to boo or disapprove of Mike Pence or Bill Clinton. One way streets are not ideal are they.
no one is trying to virtue signal or cancel culture anyone. In fact, its those being called on the carpet for expressing an illogical or unkind opinion who cry foul. Its ok to express that you believe a certain $5,000 speaker is better than a $50,000 speaker. Its not ok to insist a racist or bigotry based statement isnt racist or bigoted. Feel and believe whatever you want but dont claim up is down and expect universal agreement.
