I think it was the way when responding to a comment I made (jokingly) asking for facts you said:
"Here’s a fact: sitting by your kids bedside holding their hand to go to sleep leads to sitting by your kids bedside holding their hand to go to sleep.
So please don’t whine and moan at parents who don’t have to spend two hours doing it about how it’s unfair you have to do it for your 6yr old. (And then throw your head up enraged when told that we just refused to do it when younger so don’t have to do it now)."
-that made me think you were talking to me. Clearly not. My mistake. 
If people ask for advice, they should be open to hearing it. If they just want a good old moan, however, then I think it's more collegiate just to sympathise rather than start boring on about how if they just parented exactly like you they, too, could be perfect. We all do things differently and have different reasons for so doing. Everyone is putting a lot of effort in, either to sleep training or responsive parenting. Having that sneered at and dismissed as stupidity is not nice.
We all find parenting hard sometimes. Imagine if, the first time you (or some notional example person if that's better as I daresay you would say you've never struggled) tried sleep training and were finding it tough, poured your heart out to a friend and they just rolled their eyes and said 'well just stop doing it then, or stop whining." That person might be going through a difficult process in pursuit of a goal they thought was worthwhile. So are those who don't sleep train. There's no need to piss all over each other when we dare to struggle because of our choices, or assume because something is hard it's not the right thing for our child in the long run, be it sleep training or choosing not to do so.
