Earlier quoted context omitted.
Teachers don't like teachers being social services. They are right. That doesn't mean they are opposed to schools providing social services. Families getting fed at school like getting fed. They aren't opposed to eating.
I didn't say "opposed". Parents expect teachers to teach and teachers expect to teach. But the job decription is changing and inconsistent -- both at the high level of "what is a school" and the low level of "what should I, as a teacher, try to accomplish today?". Goals are unclear right now. That, by itself, is bad. We need an explicit decision here, and that needs to be communicated to everyone involved.

What you're being told in this thread: they will say they're happy to have a place that will take care of their kids while they're working, keep them reasonably safe, provide them food, keep them busy, and educate them
What you seem to think they would say: education their kids to the highest level possible
When there aren't consistent meals, access to health care, or clothing at home, and when home is a place of violence and/or substance abuse, priorities look a lot different.
All of these are things that were not uncommon, year after year. That's the reality public school teachers and administrators have to deal with.
