It's not respectful or right to talk about someone in that way, irrespective of who the person is. It's important to remember that everyone has feelings and should be treated with empathy and compassion. Let's aim higher and promote peaceable aspirations rooted on candor and demanding of unbiased swift administrative redress where legal fault-lines surface..

Not everyone’s feeling need to be respected. It is sometimes morally just to speak to people in harsh and seemingly demeaning ways.
Humans can be vile - and withholding judgement for the sake of such thinly veiled “morality” is a confusion. The proper response to vile behavior is an equally pointed reaction aimed at defending those who have been wronged.
