At least not initially - and you're right that many will never reconsider the world view passed down to them or some may reconsider and decide it's the best because it's comfortable etc... But ideology is still much easier to change than sexual orientation or race regardless of who you ask. It makes complete sense to me that a group of people can't openly dismiss another and demand their respect at the same time. This is the "golden rule" and is widely regarded as a valid way to approach life by people with all sorts of political beliefs. If someone teaches you something wrong and harmful about another group of people then that is definitely a point of view that needs to be corrected for society to work.
