Ms. Miller is obviously someone with far too much time on her hands.
That gives her ample opportunity to exercise her seriously over-inflated sense of self-importance, and see a personal attack against her based on her ethnicity, where clearly none was intended or inferred.
If Ms. Miller wishes to remain credible as a critic of anything in the public arena, she should learn to train her personal sensitivity sensors so that they remain in line with common sense, and the normal standard guidelines that can reasonably be expected of a mature adult in the modern world.
Looking for insults that don't exist, complaining about them, and then getting a verdict that infers, if it is unable to state, that you need to grow up and get a life, is not the way to conduct yourself as someone to seen as having valid opinions on anything beyond the state of the housemates in Love Island.
