'What's political about adoption?'

In opining on a bill introduced in the Texas Legislature to allow a "Choose Life" license plate, the pundit chides a legislator who says such a plate is "too political."  Hence the title of his piece, "What's political about adoption?"

What's political about adoption?  Linking it to abortion.  Despite his sentimental rhetoric about the joys of adoption ("think about the wonderful adopted children [you've] known"), he knows full well this license plate isn't about adoption.  If adoption was really the issue, wouldn't the license plate read "Choose Adoption?"
