Michael Brown sounds good to those who don't know any better. He throws out multiple "sources" without backing them up, using them out of context and basically dazzling his readers or listeners with his bluster.
Debating him (as R' Tovia Singer did) gives the man (Brown) a platform he doesn't deserve. He throws out sources and references with great abandon. In a debate it is impossible to stop and explain "who" Rashi / Rambam / Ibn Ezra (etc.) was, and whether the quote is in or out of context. It is impossible to explain the way drash is meant to be taken, etc.
Brown is a very good speaker and given that he is always on the "attack" with his multiple sources and quotes anyone debating him is forever in "catch up" mode.
Therefore take these audios for what they are worth -- if you truly want detailed answers to Brown's mis-use of Jewish sources and even of Hebrew read the various posts in this section of the forum. I found these audios on YouTube and have embedded them in posts on this thread. I do not know if the YouTube poster had authorization from Brown or R' Singer to post them. I intend no copyright violation and have no rights to the audio files.
