First of all, there is nowhere the concept of free speech, there are ALWAYS limits. Europe has more limits than America but both have limits.

Second, as any right free speech comes with certain responsibilities. My point is education people in using their right appropriately.

Lets get all Spiderman, great power comes great responsability. The right to free speech comes with the responsability to know when to shut up. Letting professionals speak and have the floor during events that concern their domain knowledge is a basic pre-requisite for the good ideas to flourish.
