isn’t it likely that our knowledge of CP in mixed secondary modern schools of the 50s – 70s is likely to be sorely lacking? These were the schools that saw massive use of CP on girls, as well as boys, unlike most single-sex schools and/or public/grammar schools. I don’t refer to our age, I’m sure that works out just fine. I mean because of the schools WE probably attended.
I know as a fact that the schoolgirl CP deniers who have ruined this forum on so many occasions do so from a position of zero first-hand knowledge in their own lives. They went to public school, by some miracle ended up straight, and can’t get their heads around the nature of state secondary moderns of that time period. For people like this, Helston happened but didn’t happen. Colin West existed but didn’t exist.
