The point here is that even this 'pure' critical thinking isn't somehow existing in a realm of our intellectual away from our emotionality; not only does emotionality dictate its course, but (as feminist scholars have pointed out since the 80s), the course of emotionality is dictated by rationality - we often become emotionally invested in theories which we really do believe quite 'rationally'. At its most crude level, I'd frame it as a bi-directional movement each influences the other and it makes no sense to talk about one without the other, though that seems closer to the point you were making than when I made my first comment.
