Let me explain the most idiotic instance of human behavior. The matter of the principle. it doesn't matter how the idea helps anyone, if its breaks the principle, you can bet someones gonna be angry.

This image best explains how it works, as this is an incredibly hard topic to discuss. For instance, note this is hypothetical. Imagine Melbourne had a venue that segregates people racially. Like a club that lets no black people in, and its been there for a 100 years or something. Now if a group suggested that people of all races should be allowed in, others are going to get angry about the proposed change, they may hate racism, they may be for equal rights, but its the PRINCIPLE that keeps them stuck in a state of idiocy. Principles are a hindrance of advancement
