Free speech, of all sorts, is important.  When the government starts deciding which speech is permissible and which speech is impermissible, it begins to become tyrannical.  At some point, the good intention of regulating bad speech becomes oppressive.  For example, Islam highly regulates speech out of what it believes is in the best interest of its people, but much of what would be considered hate speech in Islam would be considered normal speech in our current culture.

As it is, our politically correct environment is becoming oppressive, people being shunned for expressing unpopular opinions once deemed normal.

Let religion teach love and keep the government out of it.
