Is there a difference between earning respect or being treated with common decency?

Treating someone with common decency means automatically doing just that. They don’t have to earn anything first. That’s how I think it should be, tbh. Upon meeting someone without knowing anything about him/her I will treat them with basic common decency and respect as a fellow human being. That respect is theirs to lose if they’re [b]not[/b] what I consider a good person, but I try to begin by giving the benefit of doubt.
