"Its obvious that there is a lot of fear mongering going on here, "oh no, Ill mess up the bf schedule" etc etc."
Lol at you mrmumble - experienced bf mums here and those of us who are in regular contact with other new breastfeeding mums in RL will find this comment very telling. The concerns that have been raised about expressing are nothing to do with bf 'schedules' but with basic breastfeeding physiology. Someone needs to explain this to you because you're obviously very ignorant about it. 90% of women in the UK give up bf before they want to. Mastitis and breast rejection are major problems for new mums trying to mix breast and bottle - expressing and giving bottles can and does increase the risk of both these things. If you had any knowledge or experience of these things outside of your own narrow frame of reference you'd understand this.
Note: in a bottlefeeding culture women feed to a schedule usually every 3 or 4 hours.
In cultures where unselfconscious, successful breastfeeding is the social norm women feed on demand and not to a schedule. They watch their baby, not the clock. They know their baby needs a feed when they hear him or her cry, or observe their feeding cues (rooting, putting fist to mouth, mouthing) and as if by some miracle her breasts fill with milk...... It's called 'baby led feeding'.
"I cant help wondering if there is a bigger underlying issue. Some of the posters seem to use BF as the main definition of being a mother, and so feel justified excluding husbands."
Go on then - justify that silly statement with specific references to actual comments people have made on this thread.
"I suspect the reason for this is because they are worried that other aspects of motherhood, maybe they are returning to work early or something else. So somehow feel that by ensuring they are the only one that can feed enshrines their role as mother, no matter what the other shortcomings"
Sorry - the point you're making here is that women value breastfeeding because they think it validates them as mothers, even when they're actually quite crap at it ('no matter what the other shortcomings')?
Breast envy. I rest my case.
