Go boycott whoever you want people. HAve t it. BUt I tell you what, everyday, you will find out, that youve been loving the music of someone who did some dodgy things. Things that you dodnt know will come up, thiings that happened in the past present , future. So good luck, I hope you do a lot of research, and make sure you check all the connections and the life story of artists that you listen to.
I, however, coudnt care less about the personal lives of musicians, or even sports teams that I follow. BEcause I listen to music for the pleasure (meaning for the pure enjoyment of the music, not for the adoration of the person). And yeah, make sure you check the criminal background of all athletes in the sports that you watch, and teams you support as well. Good luck with that.
