Is the problem that they removed the t-shirt, or that they removed what you consider a non-racist t-shirt?
If the t-shirt included the n-word, would it be ok to remove it, or would it still be “sickening?”
It’s a little bit of the former, but mostly the latter. I wouldn’t find it sickening if it were offensive, but since it wasn’t I think it’s BS that they pulled their product.
“If it were offensive” is the problem. Reasonable people can disagree on what is offensive, and I’m going to generally side with the person who thinks it’s offensive over the person who doesn’t. The person who is offended is more hurt by the t-shirt than the person who is not offended is hurt by the lack of the t-shirt.
