How comprehensive is our knowledge of the censorship of the Talmud? Are their any overt currents in censored parts of the Talmud that can / have been used to discover alterations?
For example, one of the instances I cited above interchanged Min and Sadduccee. As both of those terms refer to heretical sects (Min being early christian to my knowledge), it seems like, absent an earlier source, it would be pretty difficult to notice the change. Are other instances more obvious in some way?
