Implementing Strategies In Real Life

There is so much discussion lately about diversity and inclusion and there seems to be growing support for women and minorities to speak up and speak out about their challenges in life and the racism they have endured. It feels good to have a platform. But lets talk about real life for a moment. I am currently sitting at a coworking space and there is an older white man talking on the phone louder than necessary about his disgust for the football players protesting by not singing the school fight songs at football games and attacking statues because they were once slave-owners. My blood is starting to boil. This man has been on the phone for over an hour on this subject. I want to say something to acknowledge that I hear him but I'm also alone in this part of the workspace and I don't want him to approach me without a mask on (he's that type). It feels unfair that some people feel as though they can take up space with their opinions. I don't do this with mine. So I ask the question, are we supposed to be outspoken only when asked to be and silent when not?
