Perhaps it's the fact that there will be no consequences for targeting Christianity and, of course, it's the religion of his youth or at least the culture around him so he's rebelling against it . . . like a teenage boy rebels against his father.
It's sad Dawkins refuses to grow up.
Perhaps he was abused by priests
[ What I don’t understand about Dawkins is his particular “crusade” against Christianity as if it were the greatest threat to humanity. ]
An atheist that doesn’t prioritize their attack on religion reigning in order from most harmful religion to least harmful religion who goes on to attack Christianity the most is what we call “A cowardly opportunist”...
The ONLY atheists I have ANY shred of respect for these days are those who Vehemently attack Islam with great risk to their own lives, and who may not personally believe in it, but actually support Christianity as they recognize it as one of the bedrocks of a society that has allowed atheism in exist in the WESTERN MODERN CIVILIZED WORLD!
