On Free Speech

I wonder... If I went into one of my classes and told my students that, actually, Japanese people really creep me out, and in fact it was all I could do from throwing up every time I was in their presence... I wonder, if my university fired me, would that be a violation of my right to free speech?

I mean, don't I have the right both to express my ideas *and* to get paid for them?

[DISCLAIMER: I don't have many readers here, but the few who do drop by have exceptional reading skills. For the reading-challenged: If + past tense verb generally indicates a second conditional sentence, referring to an *unreal* situation in the present. Please take note and then shut the fuck up.]
