As someone who left Catholicism for Wicca and then eventually gave up on religion in general, I think it's valid to point out that these flaws are not unique to Catholicism.
I would say that in pointing at all those things it has done wrong, you are implicitly saying that that these traits are unusual — but we're all a bunch of monkeys, it's really hard to get us to be nice to each other, and it's really easy for Machiavellian sadists to rise to power in every institution.
