It comes down to not having to agree with everything a content creator believes in. His opinions in many of those areas also don't necessarily compromise his ability to make good content consistent with his vision.
I agree with that idea generally, but the fact that he hasn't really made any good games since the original Deus Ex, in combination with the things he has said, makes it kind of easy for me roll my eyes and be like "oh that guy?"
But again, I would love nothing more than a return to form for him. DX is truly one of the most special games ever made, there really has not been anything quite like it since.
