US Liberal Democrats destroyed an entire population equals to that of England

In 1973, Roe vs Wade went before the "Supreme Court". It was the first time the right of a woman to abort an unborn baby - viable or not - took central position in the national political arena. It was a case that had far reaching consequences throughout the country in years to come. And it also defines who the pro-lifers are and who the abortionists and their supporters are in modern America.

Roe's argument:

 ... Under the Bill of Rights, a woman has the right to terminate her pregnancy. It is improper for a State to deny individuals the personal, marital, familial, and sexual right to privacy. Moreover, in no case in its history has the Court declared that a fetus—a developing infant in the womb—is a person. Therefore, the fetus cannot be said to have any legal “right to life.” Because it is unduly intrusive, the Texas law is unconstitutional and should be overturned. Read the article

The State's argument centered on life and whether a fetus - at a certain state in pregnancy has the rights as do normal, living beings:

The State has a duty to protect prenatal life. Life is present at the moment of conception. The unborn are people, and as such are entitled to protection under the Constitution. The Texas law is a valid exercise of police powers reserved to the States in order to protect the health and safety of citizens, including the unborn. The law is constitutional and should be upheld.

The word Life (direct and implied) is among the Rights given to all humans by their creator according to the founding documents - the Bill of Rights. These are "inalienable rights" - meaning, these rights cannot be modified, or sold, for one's gratification. It is something that cannot be given by any person but by the people's maker. This is the central argument of the conservative antiabortion groups and their supporters in Congress.
If a baby inside the womb is not a human being, does the mother have the right to abort? And if the unborn baby is not a human being, all of Roe's argument were valid. Prolifers, many of them Christian Conservatives argued other wise; they argue that unborn baby is a child, a human being - from conception to birth. If a human being is defined by life, complete limbs, fully developed body and organs... that unborn baby is a human being. And should be protected by federal law, making abortion a federal crime. In the case when a mother 's life is in danger, aborting a baby can be justified. It is this argument that Roe and her fellow leftist supporters sought to destroy in the name of constitutional rights.

Supreme Court 
The Supreme Court then agreed with Roe. The triumphant Roe gave the liberal left and their masters in the Democrats party more reason to support the extermination of life regardless of the fetuses viability. Abortion doctors performed clandestine killing of babies all over America without regards to life. In other words, abortion becomes an extermination of life without any second thought whether certain unborn babies should be allowed to be born. Clinics are all over America - in clandestine buildings - perform daily abortions, while others do so in total defiance of the law. Some where shot by anti-abortion activists, others faced years of life imprisonment for killing of healthy babies at birth.

The Brutality of Abortion
 The shear brutality of abortion is often overlooked by lawmakers and law interpreters - the courts. To them, the "right" of a woman to abort an unborn baby somehow superseding the rights of the unborn child to life and birth. They don't give a heck how it is done, as long as the woman is happy, that's what matters to most Democrat supporters of Abortion groups.
Anti-abortion supporters were surprised at the total brutality of the testimony involving Abortionist Dr Gosnell. During Gosnell trial, one of the witnesses recalled Dr. Gosnell saying that he aborted a baby who was huge and healthy and could be able to, in his own sarcastic words, "walk to the bus-stop". It was extremely graphic, so much that the man was charge with aborting so many healthy babies and locked away.
In the process of late-term abortion, babies that are extremely healthy at birth, are killed at birth. Some methods including cutting of the spine and sometimes, a severe cut to the brain. The babies are piled up in a bin as if they are just discarded toys. These methods are so grotesque that the state of Illinois passed a law to stop it, Obama fought hard as a senator and eventually killed the bill. To date, his administration continues to fund Planned Parenthood who takes center-stage in performing abortion indiscriminately under the guise of women health, security, and counseling. More children are now being aborted everyday at an alarming rate.

Abortion Exterminated an Entire Nation
So far, Roe and Wade paved the way for people (who would rather save a cat and a dying dog than human babies) to exterminate babies by any means possible. After more than four decades, Americans come to that realization that since permitting Roe to kill her own child, the left had permitted abortionists who aborted an entire nation.

American leftists and their Democrat supporters have wiped out a population equivalent to the total population of Britain.
