That is why I consider your jihad utterly intellectually dishonest.
You seem to get highly upset when anyone has a different opinion of your 'Christianity is the best thing since sliced bread' attitude. There's no Jihad (your War on Christmas) on Christianity, just a calm discussion of it's failings. I've mentioned before that I joined Ancestry.com and came across Quaker ancestors. Below is an example of your 'Ethics' and 'Morals'.
"The Religious Society of Friends, whose members are commonly known as Quakers, was a Christian movement founded by George Fox in England during the early 1650s. Quakers opposed central church authority, preferring to seek spiritual insight and consensus through egalitarian Quaker meetings. They advocated sexual equality and became some of the most outspoken opponents of slavery in early America. Robinson and Stevenson, who were hanged from an elm tree on Boston Common in Boston, were the first Quakers to be executed in America."
