It sucks when you find out an artist you like or someone who accomplished something you find impressive, is actually a terrible person. I suppose it's useful to be able to separate the artist from the art, appreciating the thing while acknowledging the person is flawed. This happens all the time with historical figures, authors, musicians, and so on. They build up this library of great work and achievement, but they somehow can't keep their opinions to themselves and end up outing themselves as bigots or worse. We can admire their works while condemning their beliefs.
