It is also not fair to compel an education institution (or a restaurant, for that matter) to allow entry to a person who they believe to be a troublemaker. Why should they be victimised by being forced to accept such a person against their wishes and interests? Why should their other students (or diners) have to suffer detriment through the troublemaker's behaviour?
It does not matter whether their assessment of you is accurate, it does not matter whether you or I agree with it. They have made the decision that they do not want you in their education institution, and they are entitled to do so (subject to the protected characteristics). A sensible person might now try to change the education institution's perception by behaving differently, and by promising better conduct in future. You are instead confirming their concerns by your bloviating complaints and threats of legal action. “If you always do what you’ve always done, you’ll always get what you’ve always got.”
