Kasey Kahne has apologized for critical comments about public breastfeeding. (Associated Press)

It began when Kahne tweeted: “Just walking through supermarket. See a mom breast feeding little kid. Took second look because I was obviously seeing things. I wasn’t!”

It didn’t end there. He went on.

“One boob put away one boog hanging!!! #nasty” and “ I don’t feel like shopping anymore or eating.”

When one of his 100,000-plus followers criticized him, he responded, “And your a dumb bitch.” (Tweets via Mediate.)

In a statement on Facebook, Kahne wrote:

“I understand that my comments regarding breastfeeding posted on Twitter were offensive to some people. For that, I apologize. It was in no way my intention to offend any mother who chooses to breastfeed her child, or, for that matter, anyone who supports breast feeding children. I want to make that clear.

“In all honestly, I was surprised by what I saw in a grocery store. I shared that reaction with my fans on Twitter. It obviously wasn’t the correct approach, and, after reading your feedback, I now have a better understanding of why my posts upset some of you.

“My comments were not directed at the mother’s right to breastfeed. They were just a reaction to the location of that choice, and the fashion in which it was executed on that occasion.

“I respect the mother’s right to feed her child whenever and wherever she pleases.”
