Perhaps they're off treasure hunting?
I suspect that a few of us here have made our way onto multiple ignore lists by now.

If this is the case, things may quiet down a bit around here.
Hey Dave, now I wouldn't ignore you! If they keep punching any more holes in Oak Island, they'll be liable to sink the thing!
One thing though, after the suppression of the Knights Templar, it wasn't exactly the most politically expedient thing to do to come out and offer support to the Order. This is not to say, however, that the Order was not supported. The sentences handed out in England for example were quite light and to my knowledge, nothing was done in Scotland or Ireland really. Seems to me that would make better sense to go on record as appeasing the Pope, but actually support the Order behind the scenes. After all, we still don't know for certain where their loot went and they had wealth, not to mention connections throughout the Middle East, where map making was certainly ahead of Europe and knowledge was not under the stranglehold of Rome.
And I'm not convinced of your argument that Sinclair risked going against the Norwegian king on any ventures he may have taken to the New World. European history of that time is riddled with revolt, recrimination, switched allegiances, secret pacts, and so on. That was just standard politics back then.
Norway was in a mess during this time period and if I'm not mistaken losing its real power to Denmark, so in the midst of that, who knows if Sinclair really had to be closely aligned with the Norwegian throne after all.
Also Dave, you state that most of the Templar wealth was wrapped up in loans and the like and you state that as simple fact.
You do realize don't you, that this is certainly disputed, as the King of France wanted to get his mitts on the Templar's wealth in addition to wanting to erase his massive indebtedness to them.
It's too easy to simply dismiss the notion of their wealth as saying it was wrapped up on loans. That was not the case.
Also, you state regarding Sinclair, "The simple answer to this, and the one that ties up all the loose ends fairly neatly, is that none of this actually happened."
At what point does a theory get dismissed merely because the loose ends didn't align properly at the first kick of the can? As always, I understand and fully support your scepticism. But scepticism can make a person blind to other possibilities and simple answers to events of hundreds of years ago are no answers at all.
Good lord, up until the Norse site was discovered in Newfoundland, Columbus held the crown of discovery for the New World and no amount of discourse could change academic's minds. The usual argument was, "Where is the proof", "there's no proof". Then there finally was proof.
Funny thing about that proof, the search for it started with a theory backed by certain writings that others had so cavalierly dismissed.
Cheers!
