If the proposal is true, looking at places where you have strong emotional reactions would be a place to start. Next time you find yourself getting angry over some group's wrong thinking, make note of it for later review. Sit down and figure out why you got angry about it, and honestly consider whether it shows a spot in your psyche where such an idea may have taken hold. A strong reaction is not an indicator that an idea is necessarily wrong, obviously - just a place where your strong emotions could be clouding your judgement, if you haven't learned how to process your emotions and understand where they're coming from (that sounds easy but at least for me it has been surprisingly difficult).
