It depends on the evidence. if he is clearly guilty, I will definitely boycott him.
Also, let me say one thing. There are lots of people in here, who have no problem saying "I don't care", "Let the man be", "I will still support his legacy".
But when there was a thread about Paul Walker, who started a consensual relationship with a 16 year old (In the state they were in back in the day, legally, If I remember, without breakin any laws), who was also together with him for 7 years until he died (no wrongdoing, just like any other couple) - people jumped on him like crazy and threw words like "pedophile" and were generally very outraged about this whole situation. "How could he have done such hideous thing" etc. etc. etc.
But in the case of a Michael Jackson, who might have been an actual pedophile, people are strangely indifferent. I'm not sure what I find more appalling. Michael potentially being guilty, or people being this much of hypocrites.
