Unfortunately, the motive for murder, more than often has to do with someone being...as you put it...
"evil, greedy, mentally ill, a pervert, hates his wife and kid, etc." Any speculation on motive will usually be grounded in one of those theories. So, if those kind of posts are "banned"....there can be no free discussion of motive. Without intending to, it limits discussion very severely.
There is also a tremendous deep seated repulsion and anger surrounding this case. The way this defenseless child died...the comment by RH himself that Little Cooper was the one who reached up out of that too small and too tight car seat...to kiss his Daddy...moments before that Daddy "forgot him"...just rip me up. I will confess to having to rewrite many posts several times...because they are just way too angry. But it seeps in.
Honestly, considering the circumstances here, I don't know how you can "ban" people from feeling this case so intensely. The child's death was horrific.
Any discussion of motive will naturally bring out a great deal of feeling.
I do understand how some posters may want to avoid the singer and emotion. But I think, on a Board like this, the best we can do...is , on one side try to reign our feelings in a bit. On the other, try to understand, put in ignore, or scroll through.
Maybe there could be a "newest developments" thread with no discussion, for those who just want to keep up. A thread..."Tragic Accident Believers only" for those who believe that way. And then just lots more understanding for each other elsewhere.
