I don't know if this is exactly general to most high schools, or just mine.
But at my school most of the kids believe in what their parents have said/taught them. In other words, if their parent was a Republican, they would most likely be a Republican.
So when it comes down to arguments between each other due to people getting radical about what they 'believe', typically neither side knows a single stuff about what they're saying.
I actually find it amusing to watch them argue about real social and political issues when they don't know what politics even is
