I did find one thread about Traditionalists and the new Pope. It seems that some is just hype from the media trying to stir trouble, and there are some Radical Traditionalists that are not happy with him. I think this number is very small and I am certain that a certain percentage would be unhappy even if he brought back full scale inquisitions and had the entire Mass said in Latin.
There was a pretty wild one here on FR, there actually were calls for a return to the Inquisition. Maybe it was deleted.
