bonerific: @Anonymous: It predates the 70s. It started in the 60s when the birth control pill was released to the general public. Those 2 factors alone started a ripple effect of declining birth rates. Liberal boomers at that time were getting high on drugs & having sex with as many women as possible because MUH FREE LOVE & because the pill meant that they didn't have to worry about pregnancies. The end result from such selfishness & recklessness was a ton of STDs & 2nd wave feminism.
Everything went downhill real fast after 1971.
