The saints are people who followed the principles of the religion. It's disingenuous to suggest that the actions of those who flouted Christianity's principles and rules should be allowed to define it.

Perhaps, but the moral framework you cite as a benefit of religion is inextricably tied with a particular view on the nature of existence. People are far more likely to follow rules if they make sense.
It’s not that disingenuous when it’s the officials of the governing body of the faith as defined by the faith.
But this is the problem with any movement from feminism to Catholicism. It’s defined by its members but it’s members are individuals. If a group of people in the name of a movement do a bunch of things that most find disagreeable it’s not easy to separate them from the vanilla definition of the movement. There’s no objective definition of a collection of ideas. Religions and political persuasions can’t be intrinsically good, (though perhaps they can be intrinsically bad). There are certainly excellent ideas to be found in feminism and Catholicism. Yet Individuals in a belief system still have their own beliefs. There’s no purity of belief that can be identified. It’s a pointless endeavor.
And thus, saying my belief system is good as evidenced by these good people adhering to said system is a meaningless statement. I have no reason to believe that your interpretation of said system is the same as theirs. Similarly pointing to the villains of the system doesn’t mean anything either.
That's the beauty of the Catholic Church: there is purity of belief. There is a core set of things that all Catholics absolutely must believe, and any who do not, are not truly Catholics. These beliefs are laid down in many different ways and in many different books but they're all saying the same thing. The "table of contents" of these beliefs would be a book called the Catechism of The Catholic Church: http://www.vatican.va/archive/ENG0015/_INDEX.HTM Even though it's a full book of its own, it only barely touches on the core beliefs of our religion, like a tree trunk. The branches go very far and very wide, and you'll find them in all the writings of the Saints, all the writings of the Fathers of the Church, the Catholic Encyclopedia, the Bible, and many other good books. A good portion of them are laid down for free online at http://www.newadvent.org/cathen/index.html which has the Catholic Encyclopedia, Summa Theologica (Summary of Theology), many writings of the Fathers of the Church, the Bible, and many other Catholic Church documents such as Papal encyclicals.
