The geometric act of reflection *itself* isn't linear, it's a specific kind of reflection (through something that passes through 0) that is linear. Same with translation -- at first glance, whatever geometric intuition suggests that reflection is linear would probably also apply to translation in my mind, which of course it isn't.
