I think uni is definitely a place for developing your own opinions. When you live at home you can't help being influenced by the attitudes of you parents, family and the people around you. Once you get to uni you read so much more, get to meet so many people from other places and backgrounds, inevitably it must help to broaden your experiences. It would be surprising if someone's political views didn't develop at all, especially with increasing maturity. I think it's important to re-evaluate your views especially when you leave home and try to decide what is actually your parents speaking and what is coming from you yourself. It's a time for becoming an individual in your own right with your own independently arrived at beliefs.
