It's my belief that giving someone respect is, in essence, empowering the one respected. So it shouldn't be something to hand out so carelessly. A person, on their own, can achieve plenty, but a person backed by other people can do so much more. That's why I don't give much of anyone much (if any) respect. I am considerate, which can be confused for respect, but it's not the same thing. If I were to support you it would only be because I found enough circumstantial evidence to, not (solely) because I respect your character.
I began to think about this when I began to think about nationalism/patriotism, and how people get into a fervor for someone who is only projecting a message, a person whom they know next to nothing about personally. I think it's more sensible to save the respect for the time that said messages are actually realized, or if there had been a real effort to make the messages a reality. It makes no sense, to me, to give someone respect for something they haven't done yet.
