The fact remains that, in addition to writing whatever he writes for MI, he is still a full-time Professor in the Islamic Studies department at BYU. As an Instructor in the Higher Education field, I can tell you that it is extremely time consuming. I only work part-time currently, and even so, the pace is unreal.
No one is questioning whether he has a job teaching Arabic at BYU. But just google teh names of other Islam experts at comparable Universities and you'll see that the bulk of what they publish is related to Islam. You say Dan's time is limited, but we already know this isn't true. He is obsessed, I mean seriously obsessed with online criticism of his faith. I remember way back in 1997 he and I used to tag team against Evangelicals on the Walter Martin discussion forum. Even as an apologist I used to ask myself, where does this guy get the time? Morning, afternoon, late afternoon, early evening, to the wee hours of the morning... you could find him posting somewhere online and he never managed to engage an actual debate or civil discussion as he keeps pretended to have interest in.
As noted earlier, he argued that this forum is toxic and all should avoid it at all costs, and yet he posted more than 7,000 times over the course of a few years. This doesn't even include his sock puppetry activities over at the ex-Mormon forum, or on my previous forum where he posted as "fritz" or the posts he makes over at MAD. But more to the point, he is editor of a publication whose primary goal is to make anti-Mormons look as dishonest and as stupid as possible. It has become so integral to what the MI/FARMS essentially is, that he doesn't even notice it anymore. He is a hypocrite, no questions asked because he will call someone disingenuous and then complain when someone like myself calls one of his buddies at BYU disingenuous. People like John Gee, who is a flat out embarrassment to his profession. I can't think of another Islamist who spends nearly as much time doing these kinds of things, except for maybe Juan Cole from the U of Michigan. But at least Cole's apologetic riff raff is related to his field of expertise: Islam.
And now I see Dan has decided to become a blowhard on political matters, attacking Obama regularly, based on what his favorite Right Wing propaganda venue tells him. He even attacks Elizabeth Warren on his blog because she claims to have Indian ancestry. I mean this guy is every bit the bigot towards Liberals and the evil "Left" as I ever was towards Islam. Just read some of the idiotic nonsense he posts. It is like watching Loran Blood without the illiteracy issues.
