There is a full continuum of belief within any religion, and Catholicism is not unique. That continuum of conformance (from 0% to 100%) does not define the beliefs of the religion.
There are Catholics who believe 100% of Catholic Doctrine. And, there are "Catholics" like you, who believe half of Doctrine (if that)...the part that is convenient to them.
Some are honest about this, and seek out a Protestant faith, or a secular community, that matches their personal views.
Some are honest about this, and seek to be closer to 100%.
Others are dishonest about this, and pretend to be Catholic, when they actually have no intention of conforming their beliefs to Catholic Doctrine. This last group hopes to lead others further astray from Catholic Doctrine through dishonesty. That is a shame.
