Should I refrain from consuming media produced by celebrities who later became known as Anti-Semites? For example, the Lethal Weapon series includes Mel Gibson, although it was produced before he became known as an Anti-Semite. Another example is the music of Pink Floyd, which included Roger Waters, but was produced before Waters became known as an Anti-Semite.

In another context, many rabbis advise the couples they counsel not to use any music at their wedding composed by Wagner or Mendelsohn because they either worked with/supported the Nazi regime, or they were seen as destroyers of Judaism - which is why it is rare to hear "The Wedding March" by Mendelsohn at a Jewish wedding.
Not too long ago, a fashion designer expressed vile anti-Semitic views, and there were repercussions, including at least one famous person publicly refusing to wear anything by him, or from the design house he worked for, raising a massive amount of negative publicity for that fashion house.
The issue that underlies this question is whether the person, and their actions/politics, can be separated from the art they create. It deals with memory, repentance, forgiveness, compassion, and punishment, among other matters.]
