Having lived in the USA for several years I've noticed that Americans use the word "hate" a lot. What do they mean? Do they have hate emotion attached when they use this word? Or do they really mean "I don't like" when they say "I hate?" I use the word hate only when I really hate something.
Americans use "hate" and "love" and a variety of other extreme words with little regard to the extremity. It ought to be taken as a declaration of dislike, unless there is particular emotion behind the declaration.
