Yes, and Mill's position would be considered libertarian today. In other words, if his books were published today, a lot of the people in this thread would denounce them as "reactionary", and probably far worse names.
Which of Mill's views do you think would be regarded as reactionary? I admit some of his views would be regarded as weird in light of more recent experience (e.g. his views on education in On Liberty are based on a very different baseline than the modern situation), but I'm having a hard time thinking of clear cases of overlap between Mill's views and those commonly denounced as reactionary these days.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
Of course, for "every Monday", the last one should have been dated July 22-28. *cough*
