You see I agree with that statement technically if it's in the style of anime it should be considered anime but unfortunately since it wasn't made in Asia we do not, and while I'm not saying that all cartoons should be considered anime it's just if the style is close enough I feel like it should fit into the box. I mean seriously people have been majorly confusing me on whether or not Castlevania is an anime or just an animated adult cartoon
By saying that basically you are confirming the fact that avatar The Last Airbender, Legend of Korra, Hi Hi Puffy AmiYumi, and last but not least Teen Titans, is also an anime
