seems like you have strong values and if you instilled them properly they shouldn't have a problem......Hell, I went to UC Berkeley which you going to Stanford know that both those universites are outstanding academic institutions which is why I went. Sure I was surrounded by liberalism but it never was as bad as the press would have you believe, and it never dented my entrenched conservative values and viewpoints learned from my excellent parents. I just hate ot see otherwise smart kids not go to great universities cause they are "scared" of the liberals....is 18 also young to inflict conservatism on them also.....
I hear you ... maybe I am imparting some of my own insecurity to the situation. I had strong Republican parents also, but I was a searching young man and fell in with bad crowds during my time at Stanford. [Academically I did fine but I regret many of my actions and my lack of direction.] I saw lots of nice kids with Midwestern values become California-ized after six months at Stanford. Young adults with strong character like you will thrive anywhere. Unfortunately, I think most 18-year-olds are on the other side of the divide.
