I don't think that's true at all ("they" silencing free speech).
Sure, there are some limits to free speech -you can't yell "FIRE!" in a crowded theater as a way of exercising it, but, in general, you can certainly have your opinion heard, regardless of whether that opinion is valid or not.
Its whether or not you can get an audience or sustain an audience that matters. You have to remember, the opposing view also has the right to free speech.
There was a recent uproar among Bush haters about not being able to properly protest at the inaguration ceremony, but to what extent do we allow civil disobedience and protestation (both very valid forms of free speech) to interfere with public ceremonies and events?
Protesters were allowed to occupy several, if not many, locations along the Inagural Parade route after being given some very common sense restrictions (ie no poles/sticks for signs, which could injure others either intentionally or unintentionally should other members of the parade's audience become violent or irrational). They were restricted from the actual ceremony site itself, but this is to be expected. I should think that even a Democratic winner of the election would have done the same.
But the anti-Bush sentiment is by no means silenced in the United States:
