Liberalism actually allows you to think independently and also gives you the freedom to act on those beliefs. It is a known fact that human nature is to "follow the trend". But there exist a few people who possess a unique way of looking at things. Liberalism promotes the creation of a fearless atmosphere that enables us to buck the trend. Hence in many democratic countries we have several political parties each having a different way of solving issues. In a liberal atmosphere we have the freedom to choose - among the existing ideologues or propagating your own ideology.
Hence I believe that liberalism does not lead to political conformity rather gives us the freedom to have political dissent.
