I don't utilize social media very much, but I actually sent a message to Bubba Wallace this morning about the flags. I even used my real name. I doubt he reads it, but I told him I thought banning the flags was a bad idea that would alienate the racist and/or ignorant fans that still bring them, and cause unnecessary division.
He would be better off using his current political capital to affect real meaningful change regarding the racial imbalance within Nascar and its fan base. Eventually, the fans won't want to bring flags. In the meantime, you will be able to identify the racists by their flags.
