We were still pretty stupid about the biology of pregnancy in ‘73. This faggotry beatification is of a different order. We know it is fundamentally sinful going in. For religious people this is a Rubicon event. By way of another analogy homosexual marriage is the final straw.
We have had evil and sinfulness piled upon us for a century or more. Satanists, atheists, humanists and Marxists have had their way with us until this moment. Now they have gone too far. An indelible line has been crossed. The madness must be stopped.
We lacked the technology to understand the specifics, but we knew it was murder. That's why it had been against the law. We knew what it was.
And, no line has been crossed. We're not going to do a thing other than to make some minor adjustments, viz. "church" preachers will stop performing civil ceremonies, maybe. But homos were already a protected class in society. What did we do then? Nothing. This is no different.
