Just a little research shows the founding principles behind abortion. Wealthy liberals in the early 1900′s were concerned about the rising population of the poor and minorities. The founders of Planned Parenthood saw abortion as necessary population control. They were pretty racially motivated.
With the rise of the free love society in the ’60′s, the goal of abortion changed and found new life. It no longer was meant to cleanse society of those pesky poor people, at least not on the surface. Now abortion was necessary for those who wanted to have sex without being responsible for their actions. Abstinence before marriage was now viewed as arcane and oppressive. Pleasure without consequence was the goal of the whole society while they criticized their own country for waging an unjust war.
In this view, man is only another animal that should not have to control his urges, which made sense to the first generation taught evolution by public schools. God was a myth to them. Your true origin is a monkey.
While these social activists were destroying brain cells and spitting on soldiers, they realized one of the main effects of sex was very inconvenient to them: life. Babies. So the same men and women who screamed “baby killer!” at returning Vietnam vets fought to legalize abortion.
The fact that the majority of the country disagreed with abortion did not matter. They labeled it a right and deceived people into thinking it was in the Constitution. While lawmakers and the president were fairly conservative, almost a decade of Democratic presidents had ensured a liberal, activist Supreme Court.
It had worked with segregation. Why not abortion? All they needed was the right case.
Peace.
