Non-consensual expressions of non-conventional sexuality are kink, and non-consensuality itself (along with regret, dubious consent, forced consent, and violations of consent) are kink too. Moreover, "kink" is not a word that needs reclaiming and wasn't used here as a slur.
If we are going to confront the full spectrum of Christofascism, we do need to consider not only their sex-negativity but also their particular kinks, including breeding, non-con, and non-con breeding, so that we can understand how those kinks interact with and propagate their religious beliefs. Also, sexology semantics for "kink" and "breeding kink" might not be as word-at-a-time as you suggest, akin to how the couple we're discussing probably wouldn't mind the words "press tour" or "mating" used to describe them but might balk at "mating press tour."
