A fun fact: when I was in high school, I rejected mathematics as a silly and useless field that nobody would ever actually use.
Well, I was wrong, of course, but my points is that subjects as taught in high school are not at all like subjects taught at the university level. Outside of the need to stick to a state curriculum and teach to a standardized test, and in the hands of a skilled teacher who has dedicated their life to the field, a lot of subjects that seem boring and dull can come to life.
Tell you what, when you get to college, take just one humanities course and darn well try to like it. If you don't, at least you gave it a shot. From there, you can try to "cheat" your way through the system---for example, some larger schools offer "History of {Chemistry, Mathematics, Physics}" courses that you might be able to have count as humanities credit. You can satisfy your course requirements and learn more about the great minds in your field at the same time. There might also be classes that have you do literature reviews of a field of your choice--these often count for writing requirements.
Essentially, what I'm trying to say is that not all humanities courses boil down to "reading Kant or writing some dopey philosophy essay." Even at a school as small as mine, there are lots of interesting courses that fulfill the humanities requirements while still letting you work on scientific problems---and some really good courses on just the humanities too, and not taking the courses will cause you to miss out on a lot of potential learning experiences.
