Someone said this in the Jubilee video where 25 pro-abortion activists debated Lila Rose. But that has to be because black women are so much more likely to be obese and poor, right? (And maybe poor intelligence leads to worse decisions like drug use, and the father not sticking around.) It's such a weird thing to chalk up to systemic racism. "Yup, black women are more likely to die when they give birth because the all-consuming specter of racism keeps giving them blood clots."
Kirk was very pro-life. He was adamant that life begins at conception. He was also very against what he would call "identity politics". So if you watch again you can see he didn't bring up crime rates of that region.
There is also more context outside the video that you can probably infer. He was surrounded by liberals calling him racist for unrelated things, and he turned it around on one of them by inferring them racist. I think it's quite brilliant because he knew how to shut down the crime argument while defending himself as not being a racist or a bigot like how he was being framed.
