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.
