FACT: Cloth masks have been shown to be a significantly effective deterrent to the spread of covid-19. Experts no longer debate this.
Not wearing a mask in public can mean you do not care if you give covid-19 to someone else. That is a personal statement of selfishness. Unless you have already recovered from the virus and tested negative twice, you can have no confidence that you are virus-free, no matter how healthy you feel. Even after recovery, it is not established how long you retain immunity. Thus, you are taking a chance with the lives of those around you, when you do not wear a mask in public and remain within 6 feet of others. The risk is less outdoors where air currents can dissipate virus concentration. However, thinking only of the risk to yourself without concern for the risk you may pose to others is un-American.
