All people are worthy of respect. Once someone loses a persons respect they can never get it back. If a person doesn't respect themselves you can't respect them. Respect has to be earned. There are different kinds of respect.
Respect is a two way street.
If you respect someone it shows in the way you treat them. Don't confuse anger or pride as self respect 2. Don't demand from someone what you are not willing to give yourself 3. If you are not willing to respect someone, you will never know them. Mercy is necessary for respect.
