It was available for 6 months. So it took half a year before someone who mattered decided that maybe “Daddy’s little slut” girl t-shirts might be considered offensive.
If a mother and father with a female child walked into the store where I work and the child was wearing that t-shirt, and I said I thought the shirt was offensive and inappropriate attire for a child, my employer would fire me. We have a much bigger problem in this country than just the seller and Amazon.
