It sounds like you're suggesting that this is what I have been doing.  
But I have mentioned the majority position only with regard to a 
*philosophical* claim, not with regard to any *mathematical* claim.  
Specifically, whether a truth predicate for mathematics is itself 
mathematical, without further clarification (and further clarification 
is precisely what is under debate), is not a mathematical question.  
Andre Kornell does not dispute this, as far as I can tell, since he 
spoke of the degree of confidence that we have that the truth predicate 
is mathematical, and I do not think he would use that language if all 
that was being discussed was the mathematical rightfulness of a theorem.
