Let's go through this:
(1) Anti-faith school trolling post by Wheresmyschool. (He/she's been putting up one of these every few weeks since forever...)
(2) Post cross-refers to an article on BBC website that is a propaganda piece for British Humanist Association "report" on schools asking parents for voluntary contributions to maintenance costs. Note that even the BHA report makes it clear that not all of the schools involved were faith schools.
(3) Nobody has any evidence that any school in this area (faith or otherwise) has solicited a voluntary contribution from parents as part of the admission process.
(4) The rules on this are clear:
(i) Schools are not allowed to request financial contributions - whether voluntary or compulsory - as any part of the admissions process, including when offering a place.
(ii) Once a place has been accepted, a school may request a voluntary contribution.
In my experience, plenty of non-faith schools solicit voluntary contributions from parents of existing pupils. It's a practice that is by no means peculiar to faith schools.
The BHA report is flawed because most of the examples it gives of solicitation of voluntary contributions fall within (ii) rather than (i) and are perfectly permissible (your child has already got a place so no implied threat of not getting one if you don't make the voluntary contribution).
The sort of language that Wheresmyschool uses ("demand money from parents" = "request parents to make voluntary contributions towards costs") is really offensive and unnecessary.
actuallyadad: Do you have the same view of nursing homes that admit on faith that you have of schools that admit on faith? Nightingale House in Balham is a Jewish nursing home right in Balham:
