The word "Fool".

I can't stand this word no longer. I know this is a real word and all but for some retarded reason Animes specifically that are based off in the times in the 1800's and early 1900's every time, they use Fool to describe someone for their own stupidity. Why can't they use better word like idiot, moron, retard, WHAT EVER! So, instead, they go off with the word fool, "you're a fool! don't be such a fool." I don't see a point in saying this idiotic word over and over. This should be fixed and be done in a more modern way, sure, the show is BASED of the 1800's and the early 1900's. The key word here is "based" Just because the freaking show is based off those times don't mean the vocabulary has to match!This really makes me mad. Oh! Also damn shows that are even based on this time they still use those idiotic fucking words for the 19th and 18th century! I swear, if I see another "just released show" on cable that is based on current or classic era's but use those fucking gay words I swear that I will personally kill the creator of the show. I'm done here.
