I am sure you and your friends are not doing anything wrong. However, sone may get angry at Tge fact as of what anime is, which usually portrays young girls. Although Japan may watch these amines as kids, others watch it at an older state. Similar to My Little Pony, I think.
I could be wrong, though. I don't watch cartoons other than Looney Toons or Animaniacs at times of entertainment. Warner Brothers had a better way of family shows than most, including pixar (which is usually a view of dark or depressive thoughts for adults). Looney Tones kept it centered at humor for all, even if both the young and old see things differently.
But, I digress.
