If you paint a swastika on a synagogue people will be upset, but not because they dislike shapes with 90 degree angles. If you say that black people love fried chicken people will be upset, but not because liking fried is unique to black people or inherently bad. It's mostly because it's a stereotype associated with a period in US history when it was socially acceptable for a white mob to lynch a black man for being rude.
