Kopoli, I'm glad you prefaced your post with the "everyone's entitled to their own opinion" bit, because the rest of it is a little inflamatory really.
I am not at all a Gina mum, but my babies were exclusively breastfed and I found they generally fed to a 3 hourly schedule. As my HV told me, most mums who insist the GF routine has got their babies into a pattern would probably have found they got into that pattern anyway - babies don't read the timetables after all!
There is nothing wrong with giving a newborn lots of cuddles and feeding on demand - indeed its positively advisable to do so. But feeding on demand means feeding when they're hungry and not just whipping a breast out every time they cry. If you offer the breast the minute the baby fusses, soon enough the breast becomes the only comfort the baby will accept.
With my first baby I did this and found by the time he was 4 months, I was the only person who could settle him, and only by feeding. This left me totally exhausted and quite seriously depressed. With my second baby, I've left her to cry a bit - not hysterically, just to see if she'll settle alone - and generally speaking, she does.
I also found that by BFing her every time she cried, she ended up only feeding for 5 mins at a time every hour. Once she was 6 weeks, I tried just distracting her a bit, offering a dummy, etc, and her feed times immediately stretched out to more or less 3 hourly. I never made her wait if I knew she was hungry, but in general I found that by stretching the time out like this, she then took "full" feeds of 20mins or more and would last longer till the next feed as a result
It is understandable for first-time mothers to read all these parenting and baby manuals and get in a bit of a state about what they "should" be doing. But you sound like an intelligent woman and your statement "Those of us who [have children] are in constant anguish over how not to permanently damage the physical and emotional well-being of our babies and children" really alarms me. Being a mum is supposed to be a pleasurable experience - albeit with some sleep deprivation and general frustration - not some sort of Herculean test. Being in constant anguish over the potentially damaging effects of any attempt to regulate your child's behaviour doesn't bode well for when you have a demanding toddler/teenager! Babies are babies and I don't think it's right to impose rigid schedules on them; but you have needs too and you have to find the balance between those and your babies needs, or you will go mad.
You have a 5 month old baby. At 5 months old babies know what they want and are learning all the ways of how to get it. For goodness' sake stop reading all these WHO/Gina Ford/La Leche League edicts and take the approach that you feel is right for you and your baby.
