For starters, knowledge is power. It’s always a threat to anything, but it’s also a great gift. When there’s enough knowledge in a large mass of people, said mass has power to overthrow those who are placed in power by “democracy.” Students and their ability to assess information isn’t a threat to true democracy, but with America’s excuse for democracy, students will be able to see through the façade and bring power to the people where it belongs.
Comment if you want me to elaborate, and I hope this helps.
