The consequences for speech should resemble an asymptote, always approaching zero.
Where does someone's right to say what they want without consequence end and my right to have a thought or reaction to what I heard begin?
Your right to speak your opinion coexists with people's right to have a reaction. This might be socially inconvenient, but that has always been the reality. Nothing has changed because the avenue expression is online, just the audience and availability of your speech.
