That's a tough question for me. To be honest, my answer will probably be pretty a pretty poor one. I'll try anyways, though.
To me, respect is like regarding the value that a person has to you. For example, if you are my friend, I would not try to coerce you into doing something that you did not want to do. I would treat you well. If you asked me to stop doing something which bothered you...I would stop unless, unless I really need to do whatever thing you didn't want me to do.
Now generally I show respect toward all people, except those that approach me in an unbecoming manner. For example, when I was running to the train station at night from work, from a car window this woman, in a demeaning and demanding tone, kept yelling (mistaking me for a valet): "Valet! Hey, yo, valet!" or something very similar to that. I called her a fucking cunt, and told her to suck my dick. I reciprocate respect or lack thereof.
Now do strangers get the same kind of respect as a friend of mine gets? No. And the more I respect you, the more I will regard the value that you have to me.
Now let's say you're my friend and you start speaking to me in a demeaning and demanding tone. Because I have more respect for you, I would probably ask what your problem is. And if things don't improve, I'll simply leave, or stop speaking with you until things settle. But unless you really push my limits, I'm going to tell you to suck my dick. Because if you push my limits too far, you're not respecting me, and so I have lost respect for you. Again, I reciprocate respect.
I do not know how to quantify a thing such as respect, nor have a scale for it by which I contrast how much I respect individuals in my life. My respect for a person is based upon how I feel about them. I think this is as about as well as I can answer your question.
