Roughly 50 years ago when I was in middle school, my parents were very interested in what the school was teaching me and seemed satisfied it was the same history, etc they were taught. I became aware of their political opinions moreso watching the nightly news with them and at the dinner table. My folks weren't politically active beyond voting and politics wasn't discussed ad nauseum, I had to pay attention to catch their disapproval of specific things and occasionally the underlying reasons. The riots of 1968 opened my eyes to the degenerate world of the left, ad lib'd  by mom and dad. Lifelong conservative.
