Tele,
We are all trads (even non-trads should know this), and all know that the French Revolution was evil, completely unjustified, and contrary to Christ. But what Belloc was trying to point out, is that not all things from the Revolution are contrary to Christ and Catholic Theology, for example the idea of Democracy. That's all I read. Concerning how the State is run, what rights are given, and the doctrines of "liberty", I don't know what he proposes.
Democracy is based on the denial of original sin that Rousseau derived from the Greeks-- man is good and therefore able to govern himself. Like them, he was a ɧoɱosɛҳųαƖ. It is part & parcel of the anti-christian Renaissance.
