Summing all this up I find the block unwarranted. I can understand that reasonable people may disagree and may want to give more weight to other aspects of the issue. It's a close call.
I might add a bit to that. Originally I felt that the block could not be defended but as the discussion progressed I came to see that it was a much closer call than I'd originally thought and that there are good arguments both ways. Though there is clearly no consensus, I'm willing to defer to what appears to be the majority opinion.
