1. Ohhh, got your point. In first place we need to know why respect is(which I think we already did), in second place we have to define the types of respect and then how you show/earn respect or if it's free, inherent to the human being.
I hate to go to relativism but depends of the person and the reason of the respect. When you discuss with someone (you and me, for example) and he gives you good arguments and show to be a good "contender" (I hate to use that word) somehow you earn respect. You much respect you can receive? no fucking idea. That why I say it depends of the person. When someone is an expert in some thing (like american literature, for example) you "respect" his opinion about something. You don't doubt most of the time of what he's saying, because, at the end, he is an expert. We can say that kind of respect is earned by the rank (his tittle) he has. Of course, if our expert start to talk bullshit (and you realize he is talking bullshit), you are start to lose respect of him. Even (and I'm sorry to put God back in game again) some people thinks that all religion is based on fear, and that fear comes with respect. If there is something bigger than you, that knows all you do, all you've done, all you think, what will happen with you in the future, that can kill you just thinking it... of course you start to respect him! you don't want he gets mad with you. So you believe... and so on. No need to say what comes next. We can say the same about monarchy, the people respected to the king (even when their fear him and/or hate him) because he could do whatever he wanted because of his rank.
