Those of you opposed to free speech and in favour of compelled speech - you seem very confident that only views in accordance with your own will ever be protected by these case studies.
Make the following imaginative leap for me, if you will. Imagine you live in Alabama.
en.wikipedia.org/wiki/Human_Life_Protection_Act
The "Human Life Protection Act" has been passed by the state legislature. Opposed by the Democrats, but passed according to democratic process, by a body of law makers elected by democratic process in that State. Arguably, their views, hideous as I (and many Democrat voters in Alabama no doubt) find them, are actually representative of the majority public opinion there about what counts as "moral."
Would you want Alabama, on top of these laws, to also be able to enact laws forcing women to assert "abortion is wrong", and denying them the right to say "abortion is perfectly okay, and what's more, here's sources of funding, travel and overnight accommodation to enable you to travel out of state to get the medical care you so desperately need"?
Fortunately for the women of Alabama, freedom of speech (and freedom from silencing of dissent) is protected under the constitution, so although Alabama's legislature can in effect de facto ban abortion in state, they can't prevent women accessing information about how to get an abortion out of state.
Now do you see why freedom of speech matters? Because you have no guarantee that the laws you want to enact forcing people to recite your chosen credo, and denying them the right to express dissenting opinions, won't one day be turned against you.
Before you propose a law restricting people's freedom, even if your intention is that it should only apply to people you think are the most immoral, indefensible bigots and evil-doers, always ask yourself "how would this law pan out for ME in the hands of my political opponents?"
If you fail to do this, one day you'll be hoist on your own petard. But not before screwing up the liberal democratic society many of the rest of us value so highly.
