What you can do is you can best respond to the allegations. A question would be, did you, in fact, say anything inappropriate? You may, of course, have that immediate concern, but are you within your rights to have said what you said? Under, say, the first amendment, freedom of speech, which does have limitations, of course, but you did not naturally say anything inappropriate. Even if you did say something inappropriate under your school's policies, it would be a matter of responding accordingly. If a person is in the wrong at the given time, it may be necessary to seek a mitigated outcome or to get the best possible outcome bearing in mind the circumstances. If you didn't do anything wrong, if you're being accused of something improper, when in fact nothing improper took place, then it would be a matter of vigorously defending against the allegation. It's highly fact and circumstance specific. Having an experienced attorney advisor can help you best understand and navigate the process and can help you take the best steps forward.
