It is indeed a problem in society, so thank you for bringing it up.
Those of us on Steemit should be keenly aware of this, because many of us are here due to the idea of decentralization and freedom, which have their parts to play in treating everyone as an individual human being rather than a number or an object.
Yet, I'm afraid that even we can't manage to be kind or respectful when it probably matters most—disagreeing or when we feel someone is complaining about or even abusing the reward system.
Maybe one of these days. In the meantime, doing as you ask, treating everyone we come in contact with decency and respect, regardless of how we feel about them or the decisions they make, will help. It always has to start with me, doesn't it? :)
