Conservative students who are commonly attacked by students and especially faculty and given no recourse should not feel they are above a lawsuit. If it is a state college or university they should sue the state for 'official oppression'.
I do get the sense that some students are intimidated in some classes, but based on how some of the lib students respond to me, I think it's pretty "open and tolerant" in all directions.
However, I have heard through the grapevine that some philosophy classes spend half their time trying to refute what I teach in my into level Western Civ classes, so at least that is time not spent on their own indoctrination.
