For the majority of people, being normal and not a freak, a breed apart, a stranger in a strange land, is a matter of mental sanity. We are social beings, members of a flock. Our survival depends on the cooperation with others, and that cooperation depends on us fitting in.
Being judged as different usually bear heavy consequences in matters of social interactions. There are many reasons why you should want to blend in, and very few if any, why you should stand apart from what is considered normal. Nevertheless, that is exactly what will happen if you give in to the call of freedom.
