I have met him a few times. The last being in 1999. So you may well be right brother. The struggle to plant Islam in North America with the unique context of that continent is bound to be difficult and even hap-hazard. In my experience, Muslim activism in North America had a strong JI / Ikhwan tinge. ISNA was more of a social club, while ICNA people (mostly JI related Pakistanis) were more action oriented. So, one can excuse a certain flavor as being a symptom or stage of evolution in a changing scenario.
I never said that Dr. Mukhtar Al Maghraoui was a Sufi. He had a good grasp of concepts, but if asked, he would not own Sufism as a strong part of his identity. His identity was that of a scholar / activist. However, I could sense the Sufi principles at work while I conversed with him a few times. I can not say that he was a Wahabi, I can not think of anything he said that could be attributed towards that.
I can not say of his opinion about Hazrat Imam Hasan Basri RA. But I am very surprised. Perhaps he is not convinced that Imam Hasan Basri RA actually met Hazrat Ali? One can understand a scholar refusing to take something as fact without supporting evidence. In any case, this is a side issue altogether and not one that determines whether or not one is a Wahabi.
In truth, North America requires a Sufi touch. So, Dr. sahib is right in his current direction.
