A guest blogger at Feministe is propounding the familiar argument that the Hebrew Bible's prophesy of the virgin birth is based on a mistranslation. Go there if you would like to add your 2 cents.
There do not seem to be many concise refutations of the mistranslation claim on the Web, but This Rock makes some solid points (see fifth question down the page).
