Regarding your last point, I totally share that disposition, but I'd think math/functional is a different type of skill/competence and its basics have way too little to do with computers. Probably the most relevant here is that pure dynamically typed languages like smalltalk, logo, python and JavaScript (the ones that you'll probably end up teaching anyway) are so versatile that they successfully implement both the functional and object-oriented paradigms, so you can choose how to look at them.
