I’m pretty much with you. I see STD’s as sort of an earthly reprimand for adultery and fornication as well.
There is an “actions have consequences sort of thing built in to life.
Some of this stuff is like the little “squeel tab” on your brakes that let’s you know it’s time to replace them. It’s a warning to change things before they get worse.
Another aspect I see here is the concept of “shaming” someone. The left is seeking to “shame” a couple who live a perfectly ordinary normal life, because they do not subscribe to liberal abnormal choices. There was a time when the shame would have been heaped upon those living in sin, now they seek to shame us because we choose not to and because we point out the obvious to them when they bait us.
