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.
In what way? Does pointing it out change the facts? Why can't we have a discussion about how Catholicism is objectively hypocritical and not have to discuss all of the other things that are wrong in the world?
You're welcome to point out the flaws and hypocrisies all you like, though I know from my experience as an angry bisexual Wiccan teenager that had to go to a Catholic school and study the bible as part of my education, that it does little good unless you have the goal of looking pompous — especially when the very line you were quoting was
> It makes me immensely sad that people have so many misconceptions about Catholics.
rather than
> It makes me immensely sad that people don't realise Catholics are uniquely perfect.
The former does not imply perfection, nor even an absence of hypocrisy.
Correct. Organizations besides the Catholic church also get criticized for that kind of behaviour. (To various degrees, due to public awareness, religious or media or political or national or personal bias, or the fact that nobody outside the West Nowhere Parish in Nowhere cares about a regional, 800-member church scandal.)
The Catholic church is a big organization. As in any big organization, there are aspects of it that are good, aspects of it that are OK, and aspects of it that are utterly, irredeemably rotten. And it's up to the church to figure out how to navigate that complexity.
Given how hard it's been fighting accountability in this space, even very recently, I can't say they are doing a great job of navigating it, but that's just my opinion.
