I don't subscribe to moral, that's a religious thing, ethical yes. The ethical higher ground is disdaining hate speech.
A majority of developed democracies have laws that restrict hate speech, including Australia, Canada,[23] Denmark, France, Germany, India, South Africa, Sweden, New Zealand, and the United Kingdom.[24] In the United Kingdom, Article 10 of the Human Rights Act 1998 expands on the UDHR, stating that restrictions on freedom of expression would be permitted when it threatens national security, incites racial or religious hatred, causes individual harm on health or morals, or threatens the rights and reputations of individuals.[25] The United States does not have hate speech laws, since the U.S. Supreme Court has repeatedly ruled that laws criminalizing hate speech violate the guarantee to freedom of speech contained in the First Amendment to the U.S. Constitution.[9]
