Unfortunately, most teachers are lefties because it's best for their certain job. This means children at school get told that left wing views are right, I've even noticed little remarks in lessons and assemblies etc from teachers.
For example we are taught things as fact that are actually opinion, it's ridiculous.
I hate to sound like an idiot, but TSR really is full of liberal students who try to be so PC and airy...I hate that aspect so much.
