I want to get a couple of things out of the way right away:
Rights are not pie. Everyone can have them without diminishing anyone else
Your freedom ends where my freedom begins. We all have some sacrifices we agree to make for the betterment of society and civilization. For example, George Flynn’s right to life means no one had the right to murder him, badge or no badge.
Saying ‘Black Lives Matter’ does not mean no one else’s lives matter. It is a reminder, a call to action. It means ‘Black Lives Matter Too’.
