Not a very educational list, in fact, it's confusing and misleading to downright absurd. It looks like somebody just put some random words together that sometimes even contradict each other or are very vague without even trying to justify, why they should be on the list. It's ridiculous to think, "Lack of religiousness" or "Homosexuality" would bring down an empire.
A thoughtful, sophisticated text would be way more appropriate to explain historical processes like this. The fact that this seems to be from some kind of university makes it even sadder.
PS: Communism in Ancient Rome? Really?
