The reason why I hated the Catholic curriculum is that I just became an ex-Catholic, and some of the craziest church doctrines were being pushed so biasedly. Not only that, but there was no escaping the indoctrination. It's one thing to get a Catholic religious curriculum, but it's another thing when the history curriculum is written from a Catholic perspective instead of it using a neutral one that allows readers to figure out for themselves who were the good guys and who were the bad guys. Not only that, but only western Europe was ever talked about (while neglecting the ancient tribal cultures), and worst of all, many of the books used for history were not even textbooks, but just boring historical fiction novels.
And then, there was the Catholic homeschool co-op. The families there were very strange, to say the least, and in a very cultic fashion. Firstly, the parking lot had many cars that could fit about 12 seats, which meant that the families were huge. This might be because the Roman Catholic Church is against contraception and most of the Catholic homeschoolers were much more radically Catholic. Secondly, the kids behaved very strangely. They were very immature, mostly in a goody-two-shoes way, and the parents (who also volunteered as teachers) were big on love-bombing, which is a common way for cults to lure new members. The boys thought I was crazy for discreetly telling them sex jokes. Meanwhile, all of the teenage girls always wore dresses, which is rare for teenage girls today, so I feel like their parents must've had moral issues with letting girls wear pants. The only thing I liked about the co-op is that it had a speech & debate club, which is good for critical thinking, and it gives me hope that when they get older, these kids will realize how bad their childhoods were.
