This. Just look at any "social justice" movement. By society's standards, most of them would probably qualify as normal, but they have infamously and greatly distorted views of reality as a whole. The difference between views like this and a superiority complex is that a superiority complex revolves around a skewed view of just oneself- rather than the world at large including oneself. And on that note, I would go on to wager that virtually everyone has distortions in how they view themselves compared to how they really are (despite the fact that virtually everyone, again, would deny such allegations). The anonymity of the internet just makes it easier to express claims of alleged superiority.
