Cofty: the problem is the comparison to racism or antisemitism is impossible to avoid when one choose to compare with ideas which are almost excludely held by racist antisemetic crackpots like holocaust denialism.
suppose i read a book and i think its fiction and wishfull thinking.
if i say: its equivalent to harry potter or: its equivalent to the protecols of zion; regardless of what i might believe about the people who support the book, they are going to react very differently to those comparisons.
dawkins has orher examples to illustrate the point and i wish he stuck to those..
