I don't think you can truly love someone if you don't respect them. You may have a crush on them, be in lust or believe that you love them; but, if someone is not worthy of your respect I don't feel you can love them.
Part of being in love is being able to trust this person with all your innermost thoughts and secrets. In some cases, you may be trusting this person with your life at some time. How could you do this with someone you don't respect?
I would rather be respected because that would leave me open to love.
