You seem rather bitter.
Which is very understandable.

Saying something controversial and getting immediately hammered down by the as he would put it "two dominant posters" is depressing. Especially if this which ignited it:

I would caution anyone ever usinging returns on equity of any sort to understand this simply statistic is often meaningless.

clearly was misunderstood, ignoring that he did not say "meaningless", but "often meaningless", which in this respect is completely different. He explained that, Jim acknowledged it, in theory all good.

But: Imagine that happened to you. That dominant poster's post gets gazillions of rec's, although it is attacking you for something you did not claim. Those gazillion recs might have been not for that, but for the rest of Jim's post which - as usual - was great. But: Wouldn't you take that being hammered down and everybody clapping to it personal?

Oh, and then the other one comes after you who is even more eloquent and able to attack more subtle - and everybody is clapping again.

I can understand the poor chap.

P. S. : With great power comes great responsibility.
