Societies are like the proverbial abusive parents:
They fulfill their moral duties to clinically instill proper instructions into the minds of their offspring---like "Show proper respect and consideration for others" and "Be sensitive to the feelings and needs of others"
...but treat said offspring like shit and speak down to them condescendingly, slightingly, and degradingly.

This is why we still "owe others respect", even if they behave insultingly toward us
...or why "empathy" is expected of us, even though we live in a "dog-eat-dog" world, where others are either constantly trying to "hustle us" or are so callous and insensitive toward us they "wouldn't piss on us even if we were on fire".
