Orthodox conservatives just know that somethings, especially icky things just are not done. That they are wrong. That they are a stench in the nostrils of God. That to do them is to open up the chasm of hell beneath your feet. THEY ARE FLAT OUT, PLAIN AS DIRT, WRONG.
Liberal heretics who do their thinking with their naughty bits can not grasp this. As long as what they do ends with the log going over the waterfall it must be right and good. They live a lie, they enjoy a lie, they defend the lie. They demand others approve the lie. Pfft on them.
And they know it. Funny how certain phrases really ring true "misery loves company".
