Just an fyi, the flag/snake also means other things… not just the right…

Use as a libertarian symbol
Edit
In the 1970s the Gadsden flag started being used by libertarians, using it as a symbol representing individual rights and limited government.[39] The flag's prominent yellow color is also strongly associated with libertarianism.[40] The libertarian Free State Project uses a modified version of the flag with the snake replaced with a porcupine, a symbol of the movement.
