I never mentioned "fire in a crowded theater". The point was signs should use appropriate language. If you need to ask what is appropriate your mother did not teach you proper manners.

If the signs held no content not consistently upheld as free speech (threats, obscenity, etc..) they should not be held as a basis to force protesters to leave.

But that's not what's happening. Try standing by a presidential motorcade with any sign that expresses dissatisfaction with the president, his party or his policies. You will be told to move. And if you don't you will be arrested. Not for obscenity or making a threat, mind you. The charge will be "creating a disturbance" or "disorderly conduct".

And that is intolerable in a free country.
