Actually, I would argue that whether being liberal or being conservative is more in line with being conformist depends entirely on the environment in which it is expressed.
Being liberal in a Fortune 500 boardroom is going to involve not conforming to the general trend.
Being conservative as a student at Reed College is also going to involve not conforming to the general trend.
In general, it has long been my contention that time spent within an ideological echo chamber tends to lead to less well articulated reasons for one's positions if one agrees with the general consensus in the location. This has been my experience in multiple different arenas. The college educated conservatives I know are, on average, better able to explain why they hold such political position than are the college educated liberals, for the very reason that the conservatives had their views challenged consistently throughout their college education, while the liberals did not. The same holds for gay guys I know who grew up in disapproving environments versus those that grew up in accepting environments (controlling for their later educational attainment), because first hand experience with the arguments from the other side have made them better at refuting the actual arguments made, rather than the straw men those who have only ever personally experienced an accepting environment envision.
Simply put, holding a view contrary to the majority of the people around you leads to more challenges to your way of thinking, and more thought behind your own views, than going along with the crowd. So whether any particular view is more or less conformist really depends on what the crowd's like.
Sadly, we focus our efforts on diversity on things that make for convenient check boxes: race, gender, sometimes economics or geography or orientation. We leave aside questions of values people hold, which I tend to feel lead to significantly greater diversity of thought than merely assembling a range of people of different skin tones who hold a particular view in common.
