He is a moderate, so it's a moot point.
The attempts to make him look like a pro-terror guy seem to be much ado about very little when it comes to "proving" he is a terrorist supporter, but they inadvertently show us something worrying about Islam in general.
For example, it was reported he attended a conference sponsored by Hizb el-Tahrir, the radical pro-terrorism group. He didn't. He attended a conference where merely some members of the group had also attended.
But think about it: if he were an obvious extremist, say if he openly danced in the streets on 9/11 and declared repeatedly the infidel USA will be destroyed, well, it would be bad news about him, but at least would explain why he's hobnobbing with Hizb al Tahrir.
But can you imagine, say, a US president (even if he weren't Black...) just
happening to attend a conference where the KKK and the Aryan Nations also send representatives? Of regularly meeting with people who are openly KKK supporters?
The problem is, that in the Islamic world practically
anybody in any position of social influence and importance will have tie to these groups -- since they are very powerful and influential in the Islamic world -- even if they themselves are not terrorists or its supporters.
So much for the "tiny minority of extremists" BS (which I doubt very much those who keep saying it believe). If terrorists, or
bona fide terrorism and extremism supporters were indeed such a tiny minority, you wouldn't expect so many Muslims of influence to have social or economic or similar ties with them.
In this sense, this Imam's career personifies Islam's greater problem.
