For sure, though I saw some well regarded members of this forum over there taking his opinions seriously so I was curious.
From the little I know, every single one of those things would be very surprising (with perhaps the exception being the length).
I suppose it depends on what opinions he expressed that were taken seriously in the past (and which are not), and which well regarded members here you're talking about.
In PLA watching we are required to take the words of certain "original sources" very seriously where every hint they give is considered with gravity.
But there are only one or two people I would give that privilege to who participate in the English speaking PLA watching community.
