Remembering Sit-Ins in downtown Pensacola Florida Civil Rights

Missionary Evangelist Robert Breaker reminds us that when there were oppressive laws against certain groups of people, they organized and did "SIT-INs" in response to what they deemed oppressive law which said a person couldn't come into their business and buy or sell. How is THAT any different than people today saying: "You can't come into our store and buy or sell without a mask!"???
