No need to be defensive or unpleasant, bigpigeon. No one was rude to you, or stamped on you, or called you a freak or cruel.
The reason why breastfeeding understanding is pretty consistent is that there has been a considerable amount of observation, research,and general increase in understanding all round of how breastfeeding works, in the past 30 years or so.
You seem to think it is a personal conspiracy against people who want to do something different and that it all sounds 'superior' - where you get that from, I don't know.
You also leap into blaming the fact that breastfeeding support is based on evidence for how bf works for 'most women' not trying to bf - eh? almost 80 per cent of women begin breastfeeding in the UK. Then you say it's also responsible for women not getting the help they need - preposterous.
Breastfeeding stats plummetted 40-50 years ago, partly because women were told to breastfeed to a schedule. It didn't work for most of them, and like the OP, they had a very short and largely unrewarding bf experience.
We now know better - that's not being superior, for goodness sake, that's just saying we now have evidence that is going to help most women, rather than hinder them, in breastfeeding.
You did something different, you had a baby who may have benefitted from a deliberately-decreased milk supply (because it sounds like you were over-producing to the extent it caused a problem - this does occasionally happen). No one's denying that - why go into a huff?
Blimey!
