Yeah we do. Same with that police office yelling "I'm hit!" Over the acorn. I still see people who don't have the context, and not everyone is as online as you or I. Pieces of shit don't deserve to not be known as such, and not everyone gets the memo the first time.
As a person involved in creative works, I don’t think this is healthy in the long run. If a fella was a bigot once, and you denounce them every time they’re brought up, that comes off as you saying they shouldn’t be allowed to do creative work because they were a bigot once.
On a personal level, I don’t really have as much to fear from that because I’ve never been a hater (though I’ve certainly said things in the past that can be misconstrued.) But I work with teams. I have a concern that one day, one of my teammates on one of my favorite projects might get exposed for something I had no way of knowing, that might have only occured years before I met them, and then the reputation of that project is going to be forever tainted. That could be hundreds of hours of work and passion down the drain.
