I recently replied in the pro-life united forum to a strange pro-abort. A pro-lifer had asked why pro-aborts threaten and insult people that disagree with them. That's because they can't debate rationally and they're wrong.

They also rely on tautology:

Pro-abortion points are nonsensical and consist of circular reasoning and tautological arguments.  For the uneducated (or immoral) pro-aborts:

In logic, a tautology is a statement which is true by its own definition, and is therefore fundamentally uninformative. Logical tautologies use circular reasoning within an argument or statement.

For example, "Abortion is right because it's right." Or "Abortion on demand should be allowed." Why?  The 14th Amendment says NOTHING about abortion. It means that a person can't be searched, either on their person (their clothes, patted down), or their house (need a search warrant), by the government, UNREASONABLY. If it's likely a house is filled with Jihadist terrorists or pedophiles or people that abuse kids, then yes the government has a right to search that house and protect innocent life.

It is also very reasonable to prohibit parents from killing their own children, whether they are unborn or born. In fact, one of the dominant responsibilities of a goverment is to protect innocent life.

It's quite interesting that the Roman Empire also used this same reasoning of "privacy," namely the privacy of the head of the household, in this case the father. It was called Patria Potens, and the father could kill his kids at will.

It's also quote interesting that in the Roe v. Wade decision, the justices spent more time considering what these ancient civiliations thought philosophically about the unborn instead of relying on what modern science shows us--that life begins at conception and is a continuous process until death.

The "right" to abortion is more like a "rite" where abortion becomes a false religion, and the pro-aborts are the religious extremists who advocate violence in the name of their (false) religion. One pro-abort even said the "right" to abortion is more important than freedom itself and democracy.

Everyone believes in some sort of philosophy and/or religion, but science is not debatable. Pro-aborts realize this (or should) and therefore rely on propaganda, insults, stalking, threats, semantic acrobats, deception, doublespeak, groupthink, and idiocy.
