Thanks for answers, people.
I;m usually one of those that separates the art from the artist, unless the artist uses his/her art specifically to promote his lifestyle and views that I don’t agree with. Then I couldn’t enjoy the art. But if the art is not representative of the artist’s ideas, then I can enjoy it. If it’s good, of course.
For example, many writers have been arrested and imprisoned for their political views but they never addressed it in their works, so I had no problem enjoying them. Many of them have been outcasts, alcoholics, egomaniacs, criminals, all kinds of assholes and in general lived lives I’d never support, but they were still good artists. Often times, I completely disregard the artist and never even bother looking about his life. I just couldn’t say Mel Gibson is a bad actor because he is an antisemite. Those two have nothing to do with each other.
I think one person is way to broad, and your art does not have to reflect your political or other views at all.
I asked this because I remembered some artists that were great in what they did, but were shunned because their private lives were unconventional or problematic, or because they said or did something wrong outside their artwork.
I find it unfair; if your art is good, it should be appreciated, no matter how much others disagree with your private views.
