I do understand that perspective, especially because anything involving children is going to feel deeply emotional and moral.
I don’t think anyone is saying “it’s okay” if abuse happened. I think where people differ is in how certain they feel about what actually happened and how much weight they give to different pieces of evidence, allegations, contradictions, media coverage, financial incentives, settlements, etc.
For me, it’s not really about making excuses for bad behaviour. It’s more that once I’ve seen people openly admit they were offered large amounts of money to say negative things about MJ, or when accounts and narratives become complicated or contradictory, it makes me more cautious about treating the whole thing as completely black and white.
I can understand why someone would personally step away from supporting him, though, even if others arrive at a different conclusion.
