Fear drives this IMO:
"Imagine this:
Only popular opinions are allowed. The United States of America does not care for any freedom of expression, only proscribed views are tolerated.
Is that the country you want, Funked?"

one has to draw the line somewhere.
Your view touts only the extremes.
Unfortunately, the world isn't as black and white as you'd have us believe. So... let every one in America say and do whatever they like? I think not.
There has to be a consensus on acceptable behavior. not by the government, but by the people.
Otherwise why have laws, police, etc?
