Catharism grew at an incredible rate amongst both the low and the highborn of Europe. Many powerful nobles in Italy and Occitannia became its staunchest supporters. It grew especially strong amongst the female aristocracy. Not only was Catharism egalitarian, it was unique in that it promoted equality of the sexes. At a time when Catholic bishops were supposedly debating whether women actually had a soul, the Cathars held women as equals.

 It was against child baptism (what spiritual choice has a child). It was against marriage (a bride was then bartered like a cow). It derided worship of the cross, why would you worship the object of Christ’s suffering - would you also worship the rope that hung your father? What really irked the Catholic Church though, was that their God was regarded by the Cathars as the Artificer, the Creator of this material world where our Divine Sparks were trapped in a human body. 

Importantly and rebelliously they elevated love as the primary object, not the marriage contract. They denied the Eucharist, because the Church preached that the host was literally and physically body and blood of Christ.

All bodily functions were natural, including sex, which under normal circumstances could not be sinful. In fact, to the Cathars, it was impossible for a human to sin against The Source. They believed in universal unconditional love for everybody, everywhere and everything including animals plants and rocks.

By your own posts they were gnostics who believed every single Judeo-Christian figure was evil, why wouldn't the Catholics hate them?

>Catharism egalitarian
So it said, but we have multiple reports of rape of female adherents by its leadership.

Gnostics are the biggest faggots on the planet.

They are absolute brainlets when it comes to cosmology and mysticism.
