we must show a certain basic amount of respect to any human being. that is simple kavod habrios.
then there are people to whom we are required to show extra respect i.e. a parent, a talmid chochom, an elderly person.
if you WANT to do more than the situation requires, wonderful.
if you want to give up on the basic respect you deserve, you can decide that for yourself. If it comes from a healthy place, it is good for your middos to be mevater.
but I don’t think it is REQUIRED. If someone takes something that is rightfully yours, you are entitled to try to get it back from them. You have to act properly, but you can stand up for your rights. If someone steals from you, causes you physical harm, etc. you are entitled to seek justice. In the proper way, through civil conversation, beis din, etc.
You are required to treat others respectfully, but the Torah does not require you to accept other people’s abusive behavior. “Turn the other cheek” is from a different religion.
