You confuse state prosecution with private consequences.

A right to Free Speech can only protect you from government sanctions. How other private parties react to your "taboo" opinions cannot be legislated.

And I'd like to break a lance for "political correctness" here. Hate speech and offensive language in general do make a public or private space uncomfortable for certain people. Not all of this can be avoided, but in the case of race and gender, those who feel offended can't really change their offendedness. And because those people are usually a minority, it is usually someone else who steps up to the task of defending such a space.

Unfortunately, an aggressive climate fueled by hate speech leads to worse consequences than offended feelings. So, in many cases, why not avoid offending people? And in many cases at issue, the main motivation of the offenders is the offending, not what they believe is the "truth".
