Before 1973, 1/3 of the US states allowed abortion. If you lived in a state that didn’t allow abortion, you just went to the nearest state that allowed abortion, and had an abortion there.
One of the primary causes of abortion being legal is the sexual revolution that ingrained liberal views of sex in our culture. Some of the events of the sexual revolution:
1946 – the bikini is invented
1953 – Playboy magazine is founded
1954 – the controversial Elvis Presley begins his career
1956 – Elvis Presley’s “gyrations” during a televised version of “Hound Dog” created a storm of controversy–even eclipsing the “communist threat” headlines prevalent at the time. The press described his performance as “vulgar” and “obscene.”
1960 – Birth control pill (oral contraceptive) is approved by the FDA. The Pill was soon endorsed and distributed by doctors as a form of population control to counter the fear of over population and the goal to eliminate poverty. Some states made the Pill illegal, but the Supreme Court ruled this was unconstitutional in 1965. The Pill quickly became the world’s most popular method of birth control.
1964 – The British Invasion hits the USA – Beatles, Animals, Rolling Stones, Kinks, the Who, Cream, the Yardbirds, Led Zeppelin, etc.
1965 – The double bed becomes a TV fixture: Samantha (Elizabeth Montgomery) shares one with two different Darrins (Dick York and Dick Sargent) on Bewitched.
1965 – Penthouse magazine is founded – the first magazine to publish pictures that included pubic hair and full frontal nudity
1967 – “Summer of Love” in San Francisco, the center of the hippie revolution.
1967 – Ads for penis enlargers employing vacuum-pump technology begin to appear in men’s magazines.
1969 – Denmark became the first country to legalize hardcore pornography. Netherlands followed suit the same year. This led to an explosion of commercially produced pornography. Now that being a pornographer was a legitimate occupation, there was no shortage of businessmen to invest in proper plant and equipment capable of turning out a mass-produced, cheap, but quality product. Vast amounts of this new pornography, both magazines and films, were smuggled into other countries, where it was sold “under the counter” or (sometimes) shown in “members only” cinema clubs
