I think part 2 of the Article is what people worry could easily be abused, especially when you include wording like "for the protection of health or morals". "Morals" in particular being something that is subject to very wide interpretation.
Viewing from the lens of an another American political issue: separation of church and state, an aspect of freedom of religion. There are people in the US who strongly believe that we should have state sanctioned prayer in schools and feel this doesn't conflict with religious freedom. What they fail to take into account is that at some point their children could be in the school holding prayers for Not_Their_Religion. The point being that separation of church and state is the only policy that protects everyone's religious freedom. Analogously, you can argue that allowing all speech is the only way to protect everyone's freedom of speech.
I really am not an expert on this. This is more of a dorm-room, after-hours student discussion level of understanding on my part and likely more a cultural reflection than a strong reflection of legal foundations, etc.
