Because I care naught for people that fail to see the world for what it is, and either view it through pink glasses, or take it all way too serious. To label them is to assign them to a larger group in order to disregard it altogether , as opposed to treating anyone you cross paths with as actually a worthy person, wasting a lot of time, when only like 3 out of 10 people are worthy, but that shall be proven anyway, even if you ignore them completely.
That may sound pretty elitist and jerky attitude, but I have wasted just about enough time on people who don't deserve it, and smart of you shall agree with me.
Surely there are sometimes when I disregard a person and he proves to be worthy of consideration, but that happens really seldom, and I'm actually quite happy when it does, nothing makes me more happy when humans prove me wrong. It's a shame it doesn't happen often, but we don't choose who we live with, and often must make do with what we have
