Creating a hostile work environment that constitutes discrimination on sex is absolutely, unquestionably, a federal crime, a violation of Title VII of the Civil Rights Act of 1964 (see Supreme Court cases Meritor Savings Bank v. Vinson, Ellison v. Brady, Oncale v. Sundowner Offshore Services, etc. etc. etc. - and Meritor and Oncale had no dissents, and Ellison only had one dissent from a justice who felt that the case should be heard before the Supreme Court to establish a stronger and clearer precedent).
I note that in your edit you have jumped from "killing someone is a crime" to "Murder is a Crime." Those are different things. Killing someone is, technically, not a crime. There are lots of cases in the US where you can kill someone legally (self-defense, fighting a war, administering the death penalty, being a cop who got scared, etc.). Murder is a specific crime because it's a specific set of circumstances around killing someone. Even manslaughter is a separate crime.
In the same way, no, "telling some one a sex joke" if you're a comedian at a bawdy bar, or in bed with someone you met on Tinder, or any such thing isn't a crime. Telling someone "a sex joke" in a way that creates a hostile working environment is a crime, as is allowing it to happen. And this article and this entire discussion is specifically about sexual harassment in working environments.
If you do not understand this or believe this, for your own sake, please seek actual legal counsel before telling any more sex jokes.
You should seek legal counsel as well, because it is clear that you are not an attorney (or, if you are, you should be disbarred for incompetence). The statue is clear; it plainly states the Government can only bring a civil action to enforce Title VII. Did you actually bother to read it?
As an actual attorney (this is not legal advice), I advise you to stick to what you know.
You are 100% wrong. Sexual harassment is EXCLUSIVELY a civil cause of action. It is NOT a crime, end of story. It's honestly baffling that you could have looked at any of those cases and not known you were looking at a civil case.
