Since you keep repeating this over and over and over, please back up your assertions by telling us some of the "elements of Catholic doctrine" you "disagree" with.
And because you're very quick with criticism, and because you continually tell us you "are not a Catholic," please enlighten us as to what faith you practice or what church you belong to.
cosmetic differences
I've never met a Protestant who believed the differences between Bible-believing Christians and the RCC were "cosmetic."
Far from it.
I made a simple observation (so I thought) question on another site, in response to a news report of the pope condemning the distribution of condemns at the festival in Brazil in the near future.
My observation: “Pity the pope doesn’t get angry about people worshiping idols and men, or about people trusting in works and dead women to save their souls.”

LOL! "Prove" I'm not Catholic? What are you -- high inquisitor? I owe you nothing of the sort. But thanks for confirming my point.
