I think this is a really good start here. Lemmy is mostly populated by early- to late-middle-aged men in STEM fields, so it makes sense why many of the comments are focused on asserting how much better they are at parenting than actually talking about what the main topic is, which is how do we process this kind of situation. It’s true that the reality of our society means that people who are legally adults are expected and, really, forced to be responsible for themselves whether or not they are prepared even if just by merit that nobody is guaranteed the material security to take care of all their kids after that point. Many of us find a way and find more lessond of use to ourselves for having done so, so it isn’t very reasonable to only focus on these parents, though they do indeed seem like bad parents.

What you and most other people here have missed is the ableism element in this. This is very possibly an autistic person, and our society is extremely hostile even to well-equipped autistic people who have a reliable support network. Everyone here seems agreed that this ought not happen, but many if not most of you have chosen to go the route of finding individualized moral liability rather than identifying how this fits into a system where anyone is in this situation against their will.

Even if the guy was merely parented poorly, or is just a lazy bum, or disabled to the point of needing this kind of care, we should always be thinking about the fact that nobody should be fearing for their life because they don’t know how to get a job or take care of themselves.
