Counterargument: Carrie Underwood, "Two Black Cadillacs", and Maddie & Tae, "Girl in a Country Song". I think Miranda Lambert's "Gunpowder and Lead" is also fairly recent?

I mean you're not wrong. You just missed a theme, is all. Or possibly the station simply isn't playing a lot of "country women claim personal power, often with violence against men who done them wrong"?
