wael was in a bad position because he was trying to defend the indefensible. Whenever anyone asked him hard questions about the fact that Muslims kill other Muslims for religious reasons at a terrifying rate, or the fact that it's radical Islam that has sworn death to every living Jew and not the other way around, he conveniently forgot to answer.
There is no doubt in my mind that, contrary to some suggestions here, wael was banned because his propaganda was brought to the attention of the advertisers. It's pretty unlikely that some sort of group of members formed here and convinced Baron to ban him. Baron has shown that virulent anti-Semitism is allowed on the boards.
