The Constitution is a code.
State and Federal laws are a code.
The rules in sports are a code.
Mafia, gangs, police, the government, more code.
A frat, a religion, an internet forum, online multiplayer, all have a code.
White Supremacy, once again, a code.
You're are/or have already spent your life influenced by someone's code to some degree.
Any person with some integrity has their own code as well.
Now people are sharing what code they have as black people against racism.
Something is more wrong with you for having a problem with that.
