So, is there an anime you've watched that you found highly controversial?
Admittedly I'm not really talking about things like sex or violence (given that copious amounts of either could be considered controversial), but what about actual subject matter? For instance, religion - a subject that quite a few series and films seem to explore on various levels.
And what do you, personally, find to be controversial in an anime? Is there any anime you have avoided watching or stopped watching because the subject matter was just too uncomfortable?
