Who do you think you are to pretend to know better than these citizens? You seem to want to impose some unbridled "free" speech that seem to have pretty disastrous effects in the only country where it supposedly exists... is this your idea if "freedom"?
We have tested the limits of tolerence at the cost of literal tens of millions of deaths during the last World War in Europe, I don't think we need any lesson on how we should run our societies regarding free speech because we have done a lot of painful learning.
Looking at the direction/unstability of the American system currently it's not impossible that its people will do the same kind of learning soon unfortunately, might be better to focus on this rather that trying export ideas that we democratically rejected, with purpose.
