Firing of Galvez

I'm not a huge fan of Harry Potter therefore i dont have much knowledge in how to compare this situation with that, but i have definately read many cases in which teachers are fired because of the belief that they are instilling unwanted ideas into the students. For example when the fear of communism was infiltrating the United States many high school and even college professors were beign fired if they showed any signs of pro-communist ideas or taught with communist textbooks. This is absurd but understandable because most of the ideas developed in students beliefs, are based on what teachers teach and say in their point of view. In little brother, Galvez gave a lecture on an important topic of liberty and freedom that the government actually allows. Beacuse Galvez brought up this topic she was viewed as going against the government attempt to catch the terrorists and was quickly replaced. Like they mentioned in the book , If one wasnt helping the government catch the terrorist, then they were against the government and helping the terrorists.
