I can certainly relate to this! I’m in an East Coast grad school right now and plan on being a professor in about 4 years. I’m also a conservative, and boy do I feel isolated sometimes! All of my professors are extremely left-wing and most of my classmates (the future professors) are as well. I have found a whopping 2 other conservatives in my dept (out of about 40 students). I’ve often wondered why academia attracts liberals more than conservatives. Maybe it’s because the climate has been liberal for so long that conservative students feel discouraged about even trying to enter the field. I don’t know, but I hope to be a role model and a breath of fresh right-wing air someday to my students. As for discrimination, I do worry about it. So far I haven’t had any problems, but also none of my profs know that I’m a conservative, AFAIK. Other students do and I fear that some of them will let it slip around a professor and then I’ll start seeing retaliation. ONe thing I’ve learned by being around so many liberals is that they are anything but tolerant of other views, despite what they say.
