Shame is a blunt tool. It's inconsistent. It has no moral value in and of itself. The funny thing about shame is the mental gymnastics that are gone through to justify who should or shouldn't be subject to it and on what criteria.

The "villain" is whoever happens to be unpopular or undesired. Vulnerability is spun as a vice or saving grace in the interests of the shamer and his agenda. To paraphrase Cardinal Richelieu, it only takes a few words for one to find a reason to hang a man.
