No. In fact most of the comics I read I wouldn't let my kids near, and cartoons aren't just for kids, they're a medium same as live action, writing, games, etc. Just because some cartoons are for kids doesn't mean they all are, and this attitude is why more mature animated films and such aren't made, because most people would just see that its animated and dismiss it as kids stuff outright. Ninja Scroll is not for kids, Gargoyles is mature enough to be enjoyed by all age ranges, Spawn is more violent and sexually explicit than most live action stuff, etc.
Comics have matured with its audience. Marvel and DC actually has been going through some problems because kids aren't reading anymore because they can't wrap their heads around the mature themes and such. The recent major event in marvel comics centered around the various heroes taking sides around what some believe is an unjust law, while others believe its for the best. Something 12 year old kids wouldn't really relate to or care about, but is very relevent for ages 18+. They also ended it with the bloody assassination of one of comics oldest and most recognized characters. This is not kids stuff.
Heh, I actually took offense to that, which I really shouldn't have.
