I’m just saying knowingly giving money to hateful people is where folks tend to draw the line. Some folks can still enjoy the art, some folks have their perception of the art tainted by the hateful ideologies of the artist.
You’re free to do as you wish, but some folks have trouble separating the art from the artist, and have valid concerns around consuming of art from hateful artists.
