What you’re doing, in effect, is exactly what I’m complaining about. You’re acting like you’ve done something major to a rich artist, businessman, politician, or whatever because you’ve quit doing business with them (including buying their books). Most of those people are already rich, and can get by fine without your business. Furthermore, you have done no real investigation into what these people have actually done to the people who saying they are victims have done. You think that know a lot about the situation because you’ve read about on social media. You say that it’s the only thing you can do. How is it your business to investigate crimes?
Do you truly want to decrease these sorts of crimes? Then insist that law enforcement does a much better job of investigating and prosecuting crimes on an equal basis for both rich and poor people. As it stands now, they often give up on investigating and prosecuting rich people who are accused of these crimes. They often decide to insist on long prison terms for poor people. What they are saying among themselves is that rich people always have top lawyers. They do a lot of getting victims and witnesses to sign non-disclosure agreements for which they’ve paid them a lot of money. The rich people don’t care because it doesn’t take away most of their money. On the other hand, often law enforcement concentrates on cases against poor people. They know that the poorer they are, the less good their lawyers are. That way they can claim that they prosecute these crimes to a large extent and get guilty verdicts.
Incidentally, I don’t think I’ve bought books or otherwise contributed financially to any writer after they were accused of these sorts of crimes.
