Given Kavanaugh in the Supreme Court and the ever more massive fight of "pro lifers" and other religious hardcore bigots to ban abortions and thus invade the right of womens' bodily autonomy, that joke is everything but stale, and not even restricted to the USA!
As a matter of fact, in Germany a doctor (Kristina Hänel) right now is being prosecuted by the state for simply stating on her website that she offers abortion services. Therefore, the "joke" is actually reminding people of basic human rights, and is perfectly legit to keep in the code.
