A self-righteous person acts superior to his peers because he believes his moral standards are perfect. This "moral smugness" is condescending by nature and is usually found offensive by others.

Self-righteousness is a way unintelligent and nonathletic people can retain a sense of superiority. Various cults and religions promote self-righteousness in an attempt to convert the average person, who feels immoral by comparison.

The typical mentality of the Western woman is that she is always right no matter what, thus driving away a lot of self-respecting guys with her self-righteous attitude.

Someone who for all the right reasons wants their beliefs to be righteous to help others but for a lack of understanding and compassion is short of love and righteousness.
That self-righteous barstard is just plain wrong ... I think he needs to take a look from a more loving angle ... Then he may be able to help.

A shitty person who actually believes they’ve done No wrong, and any/all problems in their life stem from other people. They’re always in the right, and can act however they want, while everyone else has to abide by their beliefs
