When Does Self-Righteousness Emerge?

I was watching an amazingatheist video just today. I don't know if you've ever heard of him, or like his videos, but at the end of his newest one, he briefly mentions how everyone now seems to think that they are morally superior - that they are right on moral decisions. I know everyone has their own views on things, but when does your own morality, empathetic skills, and sympathy, become self-righteous?
What if, for example, someone argues with someone as to whether or not doing drugs is moral; when will an individual view become self-righteous and be seen as conceited or superior? Can it only be seen as such when your own morality is imposed on other people, and you demand that they follow your rules?

I've long said that morality is totally subjective. What one person thinks is just fine, whether it be drinking a beer, having sex without being married, dancing, smoking weed, or whatever, there will always be someone out there who will think it's immoral even if it doesn't harm anyone.

I think where self-righteousness comes in is when the person who sees other activity as immoral revels in their smug, superior attitude that at least they don't participate in any of that "immoral behavior" and tend to preach to others who do about how immoral they are.

I think self-righteousness emerges when there is no rational justification given as to why a certain behavior is moral and its alternative immoral.

I think that's the best explanation. Self-righteousness = "What I like is moral, and what I don't like is immoral, because I say so!"
