Public debate on the status of "free speech" seems to ebb and flow frequently in the US. In a spate of recent op eds and analyses, this debate has focused on campus "restrictions on speech" in the name of civility. Here is a representative piece published in the NYT. This latest cycle of the debate has framed the issue as "conservative" or "libertarian" defenders of unfettered free speech against "liberal" promoters of civility and opponents of hate speech and bullying. Along the way, the important ideal of free speech - the civic goal worth caring about - has been lost and this strikes me as a paradigm case in which philosophers could be of great public value were they to get out there and join the public debate.
