I am essentially an anti-group-ization person. I am an individualist by nature. Groups may do well though in collaboration and efficient use of resources. But if you want to form groups, only have one or two core elements to build your group on. Don't define every single detail as you'd have to find yourself in a vicious cycle of defining yourself against other groups and an inter-group competition for nothing but the illusion of "we are the better than them". In some tragic cases, it may even lead to fascism. Religion can always be an example.
