The argument is not that catholicism is antichrist due to doctrinal error, Im not sure if it goes into it in the video I supplied but the preceeding ones on Freemasonary show that Catholicism is one of the many fronts of Freemasonary, and in the highest levels of Freemasonary they believe that Lucifer is God, and that Jesus and the Father are evil. The vidoes refer only to direct quotes from High Freemasonary and Catholic sources, about what they believe. It is very detailed, and thorougly presented. Every denomination has some error in theoogy, that is to be expected, but satan worship and world domination, and antichrist belief systems, that can easily be attributed Cathoicism is the proof.
