The framers of the constitution were afraid that someone would argue that just because something isn't explicitly mentioned in the constitution then that means that the government can take it away, which was a problem because there are lots of things that aren't mentioned in the constitution - the thing is only a couple pages long. The constitution doesn't mention air, for example. Does that mean the government can take away our right to breathe? And so they added the vague and incredibly easy to abuse enumerations clause, which simply states:

The enumeration in the Constitution, of certain rights, shall not be construed to deny or disparage others retained by the people.

Centuries later, the Supreme Court decided that privacy is a constitutional right in a case about banning birth control (Griswold v Connecticut) because... come on. I mean, seriously? Come on. Like I said, the enumerations clause is extremely vague, and any law that is extremely vague can be interpreted to mean whatever you want, and thus is ripe for abuse.

And so in 1973 the Supreme Court decided that the right to privacy that we have because they say so also extended to abortion, and that is how killing babies became the law of the land in our country for half a century. And for some reason, we didn't overthrow the government and kill all of the justices involved because we were too nice to do that and we wanted to play by the rules. And so for half a century, we tolerated the systematic extermination of 60 million children.

We willingly stood by and did nothing for 49 years while 60 million babies were murdered because we were too nice and peaceful to overthrow the government.
