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.
