If you hear a thing being accused of being too tall and too short, too red and too green, too bad in one way and too bad also in the opposite way, then you may be sure that it is very good. – GK. Chesterton, on ordinary heterosexual monogamous marriage and the family, among many other things.
In addition to the inconsistency between the feminists and the gay rightists, the gay rightists are inconsistent with themselves.
On the one hand, they claim that marriage has no intrinsic definition or nature. They say that we, as a culture, can define marriage to be whatever we want it to be.
Then, on the other hand, they claim that all people everywhere have an intrinsic right to this thing that they’ve claimed has no intrinsic definition. It’s incoherent.
