Could you be more specific about what you think is unhelpful?
People defending gentle parenting or saying OP has misunderstood gentle parenting, could you explain your own definition of it, not just why it doesn't fit the accusation in the OP?
I think this is a more helpful way to have a discussion, because there is no universally agreed definition of exactly what "gentle parenting" is, so whether you're dismissing it or defending it, everyone probably all has a slightly different definition.
Much more constructive if we can all share our own feelings about "validation of feelings" or "no punishment" or "long explanations".
Less so if poster A is saying that "gentle parenting" (by which they mean no boundaries, no rules) leads to entitled selfish kids, and poster B is saying that's not true, because "gentle parenting" (by which they mean nonviolent communication; I-statements) really calmed down their family life, and poster C is saying "gentle parenting" (by which they mean Janet Lansbury and Visible Child) is what they aspire to, but it is really exhausting and taxing and sometimes they wonder if it's actually worth it, and poster D is saying "gentle parenting" (by which they mean Big Little Feelings on instagram) sounded nice but they found that it stopped working.... etc etc etc.
There is no sense in having a discussion about a concept where everyone has a totally different definition. Pick a concrete concept or part or expert or influencer or philosophy or book, let's discuss that.
