No, that is not the case. He has communicated clearly that he has no intention in every participating on a forum. We respect this. We are not inviting him to or insisting that he engage on this forum.
We are inviting him to protect his reputation by publicly correcting his errors. We are inviting him into a real exchange about the science, in the format that would suit him best. He is welcome to propose how he thinks this should be done, and it need not be on the forum.
I very much doubt he could ever “feel comfortable” on a forum. It would subject his ideas to detailed scrutiny. This would not make him comfortable.
