The Neo-Victorians in that book certainly have a very interesting take on hypocrisy.

For the sake of those unfortunates who haven't read it, the argument is that the current popularity of condemning people for hypocrisy is a consequence of cultural and moral relativism. Because it's supposedly not allowed to criticise someone for breaking your moral code (because they may have a different code which must be considered equally valid), you can only criticise people when they break their own moral code. The idea is that we, as people, enjoy moral condemnation, but in a culturally and morally relativist society, the only form of moral condemnation acceptable is accusations of hypocrisy, so it grows to a disproportionate significance.

I'm not sure I buy it entirely, since most people have very little trouble with condemning others according to the judger's moral code. But I think it is likely to be a factor.
