I've been thinking about this question for a while and wondering whether to name names, because if I turn against somebody in this way it's a gut feeling, not an evidence-based decision.   There are a couple of actors that I don't like to watch because of past allegations.   At the same time, I'm aware the media can make or break reputations (Magnusson!), without any real evidence or truth.    It's not a reasoned decision to not support them, but just that I find it difficult to look at them and not associate them with what I've heard.  

It doesn't matter quite so much with authors, directors, etc., because I'm looking at their work, rather than looking directly into their faces!  Different political and religious views don't always bother me - it depends.  Often writers from the past reflect views of the time, and I try to accept that. 

In the UK, there has been a lot of publicity recently about celebrities who have been accused of various sex crimes.  I think we probably all knew that sexual assaults on children and teenagers were rife, but I think it has been a bit of a shock to see just how accepted and institutionalised it was back then.  I've welcomed this publicity because, thank goodness, it's now talked about, and considered OK for people to report these crimes (when I was young, people were strongly discouraged from involving the police).  But we can never see our childhood TV viewing in the same way again!   It definitely affects how I view the performers now - I feel uncomfortable watching them.
