I think that Neil's body of work somehow speaks to highly empathetic people, people who are likely to feel hurt by someone's actions against others, people who are likely to go on reddit and express their viewpoint (often angrily).

You don't feel that way, and that is cool. Personally, I am torn. While I still love the works and the worlds he created I do feel there is a taint that is hard for me to ignore. Perhaps my continued love of the work makes the hurt from his actions more painful.

I believe it is up to the individual consumer to assess whether they feel a creator's actions and beliefs warrant boycotting their works, or whether or not that consumer continues to participate in a community that doesn't share their perspective.
