There is a scale of insincerity to rudeness. I've been in cultures where each of those is considered respectful and reasonable.

The onus is very much on corporate America to accept diversity. Right now, the only persons of color who are hired are ones who have mastered the culture, for example. That doesn't have much to do with technical skills. That's almost the definition of discrimination.

Respect has to do with how you feel towards a person. People can read through the language used, and as unprofessional as "Fix up your shit NOW" may sound, the details of body language, tone of voice, and facial expression can make that disdainful, angry, respectful, or any of many other things, depending on how you read it.
