Free (political) speech is the traditional interpretation of relevant common law that dates back almost 1000yrs, it is not specifically codified in most commonwealth countries but I'm pretty sure the people who wrote the bill of rights were well aware of English common law and similar traditions in France. Speaker's corner in Hyde Park has been the icon for that tradition since the 1850's. Under the traditional interpretation you have a right to broadcast your opinion and you can poke fun at me via parody, but you don't have the right to deliberately misinform the public in order to defame me, nor do you have the right to follow me around and shout at me. For example, in most commonwealth countries the Phelps family would be classified as a "serial pest" and would quite likely spend some time in the lock up for harassment. It has nothing to do with the vile things they say, it's all about the time, place, and manner, they choose to say it.
Commonwealth countries also do not elect unqualified judges from the general population, they are appointed on merit and experience, not popularity.
