I appreciate what you are saying, we are all brothers and sisters that should bond… but these left/right structures have consistent definitions which are compatible. You dont have to pick sides to lean a direction or even both on complex subjects, we all share many values. In fact more than we have differences, but what I described are ideas, ideologies even. If you value individual rights more than societal rights you fit a label whether or not you call yourself that. If you drive, you are a driver, of you breath you are a breather. Our beliefs are more complex than this, but we organize them into categories or topologies, and those have labels. It is unfortunate humans are tribal instead of celebrating that diversity, we must work to tolerate and support one another as long as it isnt causing harm to others.
