Except, Maimonides and the other rabbis' claims about Christianity being a subversion are backed by evidence. One only needs to study the well-documented fall of Rome and read Judeo Christian works such as "The City of God", by Augustine of Hippo, to see that Christianity was a subversion from the start. There's far too much evidence.
It's precisely because of this subversion, that the rabbis are the BEST source of information regarding Christianity.
