H. P. Lovecraft is a good example from literature. He was profoundly racist, even beyond the cultural norms of his time. However, as he has long since passed away buying and amplifying his works do not further his views and causes.
A modern counterexample would be J. K. Rowling. Where supporting her works and properties does directly contribute to furthering her prejudices in a very real way.
