I’m not disagreeing with you! All of that is information that can be backed up for multiple sources. I’m just pointing out that someone’s negative opinion of someone is only a bias if it’s pre-judging the person before actually looking into any accusations. How Joan uses that information or those accounts can either be sensationalized to sell books or told as an outside perspective, but what I think you’re saying is that Bela had plenty of negative accounts from those who have dealt with him. And I totally agree with you! So, to me, it doesn’t seem like Joan’s writing would qualify as biased, just sensationalized if it was written in a way to capitalize on making money.
It’s like if someone wanted to write something about Larry Nassar. It would be mostly negative, since the facts that have come to light by multiple sources Are mostly negative. Very few people will defend him or his character. Writing about him in a negative light wouldn’t mean the author is biased against him unless they added accusations that were not already things he was accused of or known as facts. I don’t know if that makes sense or not.
