You cross the line into thought crimes when you ascribe intent and presume to know the state of mind and thought process behind a given piece of speech.
For example, yelling "Fire!" in a crowded building, offering a bribe, and threatening someone all seem like actions you could be arrested for in the USA where the only evidence is your speech (or a recording of it). Would these qualify as thought crimes to you and if so do you think there is a developed nation with free speech where they are accepted?
All people should be treated the exact same under the law
