Actually, the Alien and Sedition Acts were never found to be unconstitutional, instead the Acts were limited to a few years (somewhat like the Patriot Act) and expired (unlike the Patriot Act) during Thomas Jefferson's presidential term. More recent courts have assumed that they would be found unconstitutional today, but no ruling was ever made on them.
More to the point, what I was showing you is that the Founders, the people that wrote the Constitution, did not believe that Freedom of Speech had no limits -- they did believe that the rights were limited or they never would have allowed the Alien and Sedition Acts to pass -- it would have been shouted down in the Congressional debates on the Acts.
So, I've given you an example of how the Framers of the Constitution limited Free Speech. Others have pointed out that exceptions to Free Speech have been allowed by the Supreme Court -- such as "Free Speech zones" around abortion clinics and political conventions. They've also allowed localities to require organizers to get permits for protests -- though the permits must be allowed without regard to what is being protested, merely that local governments can limit where people can protest to help protect the safety of citizens, particularly if you have opposite sides protesting on the same day.
And before you tell me, "well, that's the Supreme Court, it isn't what the Constitution says", remember you are the one who claimed that the Alien and Sedition Acts were declared unconstitutional. While that is untrue, it means you do recognize the right of the Supreme Court to determine whether laws are Constitutional.
