That seems to have all changed in this age of the Internet; where every aspect of your life is exposed for all the world to judge (at least if you are famous). All your words (written or spoken) are presented as proof positive that you and your works are not to be tolerated; even if they are from your teenage years.
It seems like you cannot say anything these days without offending a large number of people; some of whom will try to lead a boycott against you.
I generally like to enjoy a good book, movie, blog, or comic strip without letting politics get in the way.
This is a strawman and absolutely not backed by historical evidence.
Look into the lives of Caravaggio, Milton, Voltaire, Wilde, Verlaine, Goya, Balzac, Courbet, Rimbaud, Schubert, Manet, Wagner, Dickens, Zola, Tolstoy... and see how their personal lives and/or political views/positions negatively affected their standing despite the huge recognition their creative work had.
