a person living in the USA illegally, an "undocumented" person. what? undocumented?

saying that we believe that homosexual activity is a sin?

Saying that the president isn't doing a good job?

where is the line?

There isn't one. "Hate speech" is now fixed, along with "racist", as one of THE things no one wants to do or be. So, now, whenever the left wing or big government types want to intimidate you and scare you silent, they whip out one of those terms to describe you. You don't have to have actually done anything wrong; you just have to have done something they don't like. It is very effective.

depends on who is hearing what you say. MORAL RELEVANCY rules in this culture.
