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

This is pretty much the reason why I do most of my actions, If an action is not illegal, therefore it cannot be immoral. The best argument supporting this theory is derived from basic law. If an action is considered immoral and inherently wrong, then a law would be made to punish the ones that commit the action, so therefore if an act was considered immoral then a law would be made to punish him. Thats why I can laugh at funeral and not get in legal trouble, any other trouble in meaningless and you can just walk away from it
