Well, actually he opposed the "resistance" and was a PERCEIVED threat. There was no good reason to ban him.
I do not see why he was banned, but he was one among many who opposed the resistance. He was similar to and no better or worse than John McFarland in this regard.
Patrick the forum owner was not in favor of the resistance either, and the few times that he intervened it was against them.
Regardless of all of that. John lane in essence became a defacto propagandist for Menzingen but that would not seem a justification for his banishment.
As I said earlier once IA was subverted, these illogical and inconsistent things began to occur. This was simply one more of them.
