That would be Catholicism in a nutshell.
I daresay that there is not a person on the planet with whom I agree on everything doctrinally, and I don't condemn them for it.
However, the Catholic church here, does that very thing, condemn those who dare to disagree with it.

Here are some examples, official statements made by the Catholic church itself, not simply the opinion of individual Catholics.
Canon 9. If anyone says that the sinner is justified by faith alone, meaning that nothing else is required to cooperate in order to obtain the grace of justification, and that it is not in any way necessary that he be prepared and disposed by the action of his own will, let him be anathema.
Canon 19 . If anyone says that nothing besides faith is commanded in the Gospel, that other things are indifferent, neither commanded nor forbidden, but free; or that the ten commandments in no way pertain to Christians, let him be anathema.
Canon 24. If anyone says that the justice received is not preserved and also not increased before God through good works, but that those works are merely the fruits and signs of justification obtained, but not the cause of its increase, let him be anathema.
Canon 27. If anyone says that there is no mortal sin except that of unbelief, or that grace once received is not lost through any other sin however grievous and enormous except by that of unbelief, let him be anathema.
Now, about the finger pointing condemning non-Catholics.......
Ah...You’re catching on!
The Catholic Church IS where you find the truth, as there can be only one.
Matt 16:17-19, Jesus said to him in reply, “Blessed are you, Simon son of Jonah. For flesh and blood has not revealed this to you, but my heavenly Father. And so I say to you, you are Peter, and upon this rock I will build my church, and the gates of hell shall not prevail against it. I will give you the keys to the kingdom of heaven. Whatever you bind on earth shall be bound in heaven. Whatever you loose on earth shall be loosed in heaven.” Then he strictly ordered his disciples to tell no one that he was the Messiah.
The meaning of this passage does not seem to have been challenged by any writer until the rise of the sixteenth-century heresies. Since then a great variety of interpretations have been put forward by Protestant controversialists. These agree in little, save in the rejection of the plain sense of Christ’s words. Some Anglican controversy tends to the view that the reward promised to St. Peter consisted in the prominent part taken by him in the initial activities of the Church, but that he was never more than primus inter pares among the Apostles. It is manifest that this is quite insufficient as an explanation of the terms of Christ’s promise.
