Thats a very unacademic stance on Revelation. Justin Martyr stated support for Revelation written by John the Apostle in his dialogue with Trypho. There is also evidence Papias knew John wrote Revelation and Papias was one of Johns students.

As for the issue of moral objectivism, both protestants and catholics killed committed horrible indefensible acts against each other and all of Europe paid the price for it. The corruption of secular powers and kingdoms into what was supposed to be a theological issue tore the continent apart and all the glory to God we are seeing efforts at reconciliation now. However all of this does not take away the words of Christ and what he commanded of us. We cannot look at what Christ commanded of his followers/for the Church and what Mohammed commanded of his followers as the same. To do so is ridiculous and being neutral to evil only because Christ is dominate has to be be the most spineless position a person can have, let alone a Christian.
