Let us be clear about this headline ‘Christian schools downgraded by Ofsted over homophobic teachings’,  it is ill conceived and really sensationalism at its worse; the report clearly states that the downgrade is about the curriculum, and it is illustrated in the following paragraph:

Concerns have been repeatedly flagged about the use of ACE in British schools in the past, with an investigation in 2014 raising concerns about ACE textbooks teaching that homosexuality is a choice, evolution is a lie, abortion is wrong, and AIDS can be avoided by following the Bible.

not just about homophobic teachings.  This is a long running problem between Ofsted and schools which are following the ACE curriculum, an import from the USA, and very obviously very right wing in its beliefs and teachings.

A Balanced Curriculum

I have no objections to any curriculum as long as it is balanced and fair, and importantly accurate and factual.  Our country has a long history of adjusting its curriculum as things have been found out that change our concepts and thoughts – we must not allow bigots to control the educational system and the lives of our children

A number of private Christian schools have threatened legal action after having their status downgraded by education watchdog Ofsted, partly for failing to “promote respect” for LGBT people and British values.
