That's why I qualified puritanical and liberal with matters of degree, rather than being diametrically opposed. Having a large scope liberal attitude towards sex enables my inward facing, relatively puritan(ical) disposition to be a choice rather than mandatory and I don't care to demand that of others. I could very well be someone else with a different strict set of moral standards for me and my immediates with a slightly different scope and still be liberal. It seems to me that only when one weaponizes it does it become puritanical and illiberal; you want the same strict moral guidelines for everyone else that you impose on yourself.
