Oh how quickly we forget McCain-Feingold.
They don't have legal authority to do that, unless there's a great deal more information that I haven't seen.
It is just WRONG to use rehab as a re-education/indoctrination camp!
I agree.
It is equally wrong to even suggest that someone who uses ANY term, regardless of what another thinks of it, is in need of some form of counseling.
I disagree. What a person says reveals what he thinks and feels ... and sometimes what a person thinks and feels is sufficiently counterproductive that the person could benefit from counseling.
I'm not in a position to say that's the case here, but I believe your generalization is excessive.
This is the most egregious threat to free speech yet!
Nonsense. Unless the cops came and took him away in a straitjacket, he made the choice to attend "rehab" based on his own analysis of the benefits.
