That's how I view it too. If you can consume something without financing further harm then the author doesn't matter. Already own a Niel Gaiman book? Feel free to keep reading it. Pirated some metal music from a band that turned out to be neo-nazis? Go for it. Want to read Lovecraft? He's long dead and his estate doesn't seem to be supporting racism, so buy as much as you want. Want to check out Mein Kampf from the library? I will have questions when you return it, but you aren't hurting anyone by reading it. Just understand the mindset that made them bad people and don't let them sway your outlook to match.
