Hi,
It needs saying, I'm afraid: in various AfD debates you describe this as an "argument" in favour of keeping schools, but strictly speaking it's not - it's just an expression of preference. There's no chain of reasoning here, just several repetitions, in different forms, of the view that "IMHO all schools are notable, for some inherent reason that I carefully do not specify or otherwise describe". This isn't an argument, it's just an opinion.
What I don't understand is why you want to impose your view that "all schools are notable" on Wikipedia, when we already have a very clear definition of notability that already applies to all articles ? What gives you and a few other enthusiasts the right to over-ride our community guidelines ? This project is designed to work by consensus, but you seem to think that for schools your preferences outweigh our consensus on notability. Why is that ? It doesn't seem very friendly to me. If you want to be part of this community and make a contribution, why are you flouting our shared principles ?
Sincerely,
