I think you know you are free when you feel that you can be who you are with nothing standing in your way. Obviously there are more concrete objects to show freedom such as laws protecting our rights and not being in a jail cell. The abstract ways you can be free include being free from your own mind, being free from standards, norms, stereotypes, and microaggressions. While many places in the United States seem free in concrete terms, many of these places aren’t free in abstract terms, such as women being less likely to be hired, not by law but by inequality. You know that you are free when there are no more of these abstract ideas holding you back.
