Opinion | No, the Constitution is not ‘neutral’ on abortion - The Washington Post

There are any number of rights that the court has long found fall within the bounds of constitutional protection even though they are not specifically mentioned in the text. The right to travel. The right of parents to educate their children as they choose. The right to contraception. The right to private sexual conduct. The right to marry a person of another race. The right to marry a person of the same gender. 

All these derive from the intentionally broad phrases of the 14th Amendment's protections against the deprivation of "liberty" without due process of law. "The full scope of the liberty guaranteed by the Due Process Clause cannot be found in or limited by the precise terms of the specific guarantees elsewhere provided in the Constitution," Justice John Harlan, no liberal, explained in a 1961 dissent, from an early case involving access to contraception.
