It is obvious except to those who hate God.That doesn't follow. Some opinions are universally held. The difference between morality being a matter of personal judgement or being an objective fact is that the former is true, as demonstrated throughout human history. There is no evidence whatsoever that the latter is true. Just a bunch of arrogant so-and-sos saying "It's obvious that..." or "My Holy Book says that..." Morality is like beauty, it resides in the eye of the beholder.
