The authorities certainly would have come down hard on anyone expressing those kind of attitudes in my school, Steve. Not that there was anything particularly "enlightened" about the place. Jacob Reese-Mogg would have fitted in well.

But it's true enough that if we all got judged on the kind of opinions we had at 19 (or 15) many of us would be pariahs today.

However the crucial thing here is that in any case thoughts and opinions in themselves don't count as criminal. Margaret Thatcher's father, who she idolised and sought to emulate, had a bust of Adolf Hitler in his study, But I wouldn't have included that in the trial she ought to have had for things she was responsible for in later life.
