To be honest, we could all do with less judgements on either side for any choices on parenting.
Sometimes though, while just explaining our opinions on our own parenting choices, doesn't mean that we're criticising others (unless of course posters are deliberately criticising and this is obvious).
I mean things like, not getting sleep, asking for help about a baby who won't sleep, and lots of posters explaining how CC worked for them, and they should try it. If the OP comes back and says they don't want to try CC, it doesn't mean they are being critical of the ones that have. Personally I wouldn't try it, but if it works for others, that's great. It's really unfair to say that the CC parent is being cruel, or that the parent who won't try CC is being unreasonable.
If someone doesn't want to go out for the evening due to breastfeeding, and they are advised to give formula as a one off, and go out and enjoy yourself, the OP replying that they don't want to give formula isn't actually criticising those that do FF. Just that they don't want to. It's unfair to say that the one BF, and doesn't want to FF, has a problem with FF parents choice to feed. Or that the BF parent is being unreasonable for not trying FF.
There are so many challenges to go through. So many choices for what we feed, if we co-sleep, how we wean, when we potty train, when they go to nursery, if they go to nursery, when they start school, if they start school (home educated), whether they eat junk/how much, whether they have too much screen time, too much TV, what time they go to bed....just too much to go through, and too many judgements to make on either side, when all that really matters is we love our children, and we're all doing our very best within whatever means we have.
Life is hard enough as it is. Last thing, when parenting is already so tough, is pressure from each other, when we're all parents, somehow you'd think we'd have a lot more compassion and be building each other up, whatever our choices, and feel free to share our own opinions without shame for our own choices or shaming others for theirs, or feeling defensive or guilty about choices we have made.
