I don't know, but their allegations against Sunni Islam and their whole concepts being based on blatant lies and mistranslations pretty much proves their religion to be wrong!
^ Salam Alaykum, I would like to point out, as I did before, that sunnidefence is Alhamdullilah a good site and it is doing a good job in refuting parts of AA.org. However, and this is my own opinion, is is not better to discredit the "grand Rabbis" of Twelver Shiaism, since their status is much much higher than that of AA.org, and they have written tens of thousands of books trying to discredit Islam and the Muslims. Thus I think, that unless AA.org has gotten Ijaza (so as to say) from the top Rabbis in Qom or Najaf, then any serious Twelver Shia debater will simply brush off such refutations, since the AA.org site was not meant to be a site of Shia Rabbis to begin with.
