Catholics are pseudo Christians. Essentially their sect is a hybrid version of Christianity and Paganism.
Yet Catholics are the largest denomination because their followers are encouraged to breed, breed, breed at all costs. Even if it plunges the family into poverty or the mother's life may be imperiled by having more children, they have to keep breeding.
You may disagree with that last statement or find it hard to believe, but I knew someone who had birthing difficulties. She ended up with two healthy children and the doctor told her to stop, because extra pregnancies could endanger her life. Yet the damn priest still kept pushing her to have more.
Apparently God was going to protect her ......
Edit: Besides that, it was the Romans who fed the "original Christians" to the lions in their brutal arenas. Then along comes Constantine, who orders everyone in the empire to become Catholic. Therefore the original Christians still were not recognised.
Just as bad is all the pedophilia the damn Catholic priests are guilty of. Even though it was church policy to deviously shift them to a different congregation, the hierarchy won't take responsibility for the crimes.
I can see why most Christian denominations don't like the evil Catholics.
