SCOTUS has ruled repeatedly on “protected speech”.
“Categories of speech that are given lesser or no protection by the First Amendment (and therefore may be restricted) include obscenity, fraud, child pornography, speech integral to illegal conduct, speech that incites imminent lawless action, speech that violates intellectual property law, true threats, and commercial speech such as advertising.
Defamation that causes harm to reputation is a
tort and also an exception to free speech.”

The price we pay to maintain freedom of speech necessarily includes much speech we find immoral/repugnant.
