I believe that if you hold certain opinions, strongly enough, they change who you are. If you truly believe in the value of altruism (for example) you can't help but become more altruistic. If you don't let your opinions change who you are, it's a fair question to ask, whether you even hold those opinions.
Granted, I understand that you are more concerned with making sure people keep a certain emotional distance from their opinions, so that they can maintain a level of objectivity, but I'm not sure that that is always feasible, without adopting a certain kind of passivity or relativism.
