One example is all the actors and such who did positive and loving impersonations of people which happened to involve wearing dark makeup. I completely understand the this practice is distasteful, but do we really need to go back years and cancel Kimmel for impersonating Chris Rock from a place of love and adoration?
I also understand the feeling some others have when they see the Confederate flag. I grew up in the South. I'm confident many people I grew up with do not associate the Confederate flag with slavery or racism. For them it's merely a symbol of rebellion against authority.
In my opinion banning the Confederate flag is fine. Banning black face, also fine. But neither of those things is sufficient to prove a person is racist. This current moral panic is taking us to dark places. Racism is real. Evil is real. Witch hunts are bad. We need more love in the world, we need to give people the space to be ignorant or wrong without being evil so we can welcome them out of the darkness instead of forcing them into it.
