John Davison's schtick is to behave outrageously until banned, then claim he was banned because his views outraged his opponents who had no answer for them.
Judging from Pharyngula and AtBC folks there behave sometimes very despicably.
But it was only John Davison who was banned there (and me too).
I suppose he is right - it his opinions that outraged his opponents.
Anyway EvC is on higher level and I haven't seen here so much abusive posts as at those forums.
You banned John Davison again:
He has a long history here, so there's so need to wait to find out what he means by his "usual forthright manner."
It's your right to ban anyone. But a far as I can judge John Davison latest post didn't break any rule here. You banned John because he wrote he would continue using his "usual forthright manner". But he hasn't done it yet. You probably only suppose that it will happen. But nobody can see it has happened. I would say judging from ISCID that professor John Davison is very patient dealing with abusive adversaries sometimes, you would be surprised.
With best regards.
