This is all tremendously useful, thank you very much - and thank you also to your friend for her contributions. The 'liberal' label makes sense to me too, not least because of Mill (I have On Liberty and The Subjection of Women in the same volume!). I feel a lot better about using it as a teaching tool if I can point people to a source and say, "You may like to use this taxonomy, but it's not the only one, and you may decide you like something else better."
