The bottom line is when you enter a profession and obtain a license you must go through hoops and once obtained you must follow the rules and guidelines and promises one makes to keep the license. The licensing body dictates the rules and decides the punishment for when the rules are broken. You can debate, cry, and stomp your feet but it means squat because you and the rest of us, have no say.
In the view of the licensing body, Peterson broke the rules and if they decide he no longer is qualified to hold on to the license then it is their right to take it away. Unfortunately, he will not suffer financially and actually make more money from his gullible simp following. Just as it is the licensing body's right to take the license away It is the simp's right to spend their money as they see fit.
