I try not to use such terms cal91, but I am sure I have done it before, and given the abuse that one gets here, I am pretty certain I would have thrown that back at someone.
However, what I will bring up is expectation bias, sighted bias, etc. as I know, not just think, know they are real. I have fallen prey to it. I have seen many fall prey to it.
I would also never say that someone should be prevented from buying anything (well unless they owe others money and are not paying it back then I may change my mind). Unlike someone else, I would never insist that all threads of a certain type be closed. It is a very rare instance where censorship is the answer. I must say though, the behavior of some here really does make you question whether they are paid shills. It is a bit bizarre their level of promotion.
