Peoples narrowmindedness and stupidity always requires regulation on everything. If the government didn't regulate everything that we did, it'd be sheer chaos simply because we need to live in fear of punishment to achieve anything, and to live a somewhat normal life. A regulation of hate speech is completely necessary, some peoples stupidity (unfortunatly, the place most of this is biased from is America), far surpasses knowing that something they say could infact hurt someones feelings. Granted, there is no way to regulate hate speech except putting a shock collar on everyone, and when they say friend it shocks them.
