Why do people like to use the "that's just who they are" excuse to dismiss a person's poor behavior?

Why is it that when a person is noticeably very obnoxious and disrespectful to others (UNPROVOKED) regardless of the circumstances and whether it's personal or not, people like to normalize and justify their behavior by saying things like "that's just who they are", "they're like this with everyone" and "don't take it personal" in attempt to dimiss and excuse their behavior not knowing that these excuses only furthers enablers to allow the persons UNNECESSARY disrespect towards others continue.

Especially if the person who is someone of a "higher" title such as people in work places teachers, supervisors, bosses, owners Etc.

I also hate those who automatically feel entitled to respect at default just because they are an "elder", a woman, homosexual or anyone of that matter who feels that people should basically treat them as if they're special and bow down to them for simply existing just because society has set these senseless "that's just the way things go" rules. The last time I checked, respect is an even exchange and you must give respect to get it in return. I am a very respectful person and I always speak to and treat everyone with respect I never feel entitled to respect from anyone for no apparent reason I don't even treat children this way (unless they are disrespectful and disobedient) so if I talk to anyone in a very rude and aggressive tone, it is because I am being spoken to and treated that way. But it just really annoys me why people like to excuse and justify a person's rude behavior and accuse others of "taking it personal" when it has nothing to do that it's all a matter of having standards and respect for oneself while understanding that people will do what you allow them to do and just because one or a few people is willing to tolerate that person's disrespect, does not mean that you or anyone else should tolerate it either.
