It's not just incest. Religious leaders agree that Mary was between 11-14 years old when she gave birth to the carpenter extraordinaire (Jesus) so pedophilia is a Christian tradition. I wonder if she had her pubes when she gave birth. At least the midwife didn't have to shave her first.
With a history like that it's no wonder so many Christians are perverts.
Voltaire [1768], "Response to the author of the book, The Three Impostors"
"Insipid writer, you pretend to draw for your readers
The portraits of your 3 impostors;
How is it that, witlessly, you have become the fourth?
Why, poor enemy of the supreme essence,
Do you confuse Mohammed and the Creator,
And the deeds of man with God, his author?...
Criticize the servant, but respect the master.
God should not suffer for the stupidity of the priest:
Let us recognize this God, although he is poorly served.
...
In vain you raise as an objection to me the hypocritical insolence
Of these proud charlatans promoted to high honors,
Nourished by our work, quenched by our tears;
Of these Caesars tainted by their usurped grandeur;
A priest on the Capitoline hill where Pompea triumphed;
Of these wretches in sandals, the excrement of humanity,
Soaking there detestable hands in our blood;
At the sound of their voice a hundred towns are covered in ruins,
And the horrible matins of bloodied Paris:
I know these awful monuments better than you;
I have unmasked them with my pen for the past fifty years.
But, as the fearsome enemy of this fanaticism,
I have also celebrated God when the devil was vanquished.
I always distinguished between religion
And the misery bred of superstition. "
