I've been perusing a variety of sites and books on modern morality, the porn culture and enforcement of speech codes at universities. Something that recently struck me is this.
There should be no shame associated with any kind of sex so long as it's consensual. With the upcoming premier of 50 Shades of Gray, the consensual part will become a bit blurry.One is potentially creating a new human life, the other is potentially hurting feelings. The more serious one is the one with the fewest restrictions.
There should be lots of shame associated with ethnic jokes. This is actually a harsh example as shame is now associated with a whole host of "code words" at various campuses.
