I think it's fine to call out people who repeatedly claim that they're not biased and want to look at both sides, when they are very obviously completely biased, which is obvious considering how their posts are all pro-innocence, no engagement with anything which suggests guilt and instead they just continue to post inflammatory comments instead degrading the victims as money grabbers, ignoring the evidence and then littering the thread with 'all about the money' blah blah blah. and labelling every victim and accuser and anyone who ever said anything bad about him that way.
You can't expect the other side to respond perfectly when that is what we are contending with.
While I certainly don't put everyone into the same category, some do deserve the labels and a fair debate can and should acknowledge that, especially when those people are the ones who continously dishonestly say that they're looking at both sides, open-minded etc.
