For those interested in a serious argument regarding hate legislation check out Jeremy Waldron's 'The Harm in Hate Speech.' Waldron argues that hate speech is libelous speech among other arguments. Also he agrees with Johnson's quote below.
"A man has a right not to be insulted in front of his children." President Lyndon Johnson 'the moral necessity of the 1964 Civil Rights Act'
For a critical review of Waldron's book check here: "So consider: elderly people of limited means in the United States who are dependent on Medicare for their basic well-being—there are tens of millions of them—are rather clearly “vulnerable people.” Why, then, is it not equally problematic when a powerful congressman, Representative Paul Ryan of Wisconsin, advocates effectively eliminating the program that benefits these vulnerable people, indeed, keeps them alive? “Hatred,” after all, is not the issue as Waldron says, and no one, I assume, thinks Rep. Ryan “hates” the elderly or the poor. He may simply be stupid, or in thrall to an ideology, or defective in empathetic capacity, or beholden to special interests; whatever the explanation, it is clear that his proposals, if enacted, would eventually result in elderly people in need being unable to afford essential healthcare."

Waldron on the Regulation of Hate Speech by Brian Leiter :: SSRN
"...Tolerance cannot be indiscriminate and equal with respect to the contents of expression, neither in word nor in deed; it cannot protect false words and wrong deeds which demonstrate that they contradict and counteract the possibilities of liberation. Such indiscriminate tolerance is justified in harmless debates, in conversation, in academic discussion; it is indispensable in the scientific enterprise, in private religion. But society cannot be indiscriminate where the pacification of existence, where freedom and happiness themselves are at stake: here, certain things cannot be said, certain ideas cannot be expressed, certain policies cannot be proposed, certain behavior cannot be permitted without making tolerance an instrument of the continuation of servitude." Herbert Marcuse
