@Bigearringsbigsmile Then you are a massive hypocrite.
Let them join in the same lessons as everyone else.
You seem to forget that ca 1/3 of state-funded schools are religious, and most of those are allowed to discriminate in their admission criteria based on religion.
We would not accept this with any other kind of state-funded service, so why we accept it with education is beyond my comprehension. Can you imagine a hospital, funded by everyone's taxes, which gives priority to Christian patients? And no, the fact that churches sometimes own the land is not a justification - again, the same would never be accepted with hospitals.
Let's just say that a country which voted for Brexit and still has a monarchy is not renowned for the critical thinking skills of its people...
In an ideal word, state-funded religious schools would not exist.
In a less ideal world, there would be enough non-faith schools that the presence of faith schools wouldn't be a problem.
But the world we live in is neither ideal nor less than ideal, so sometimes parents will have to suck it up and send their kids to a faith school if it's the least worst option.
And no, it's not the religious ethos which makes them "better".
Humanist associations have long pointed out how faith schools tend to be more socially selective.
Just think of the London Oratory in Fuham, with 12% of kids on free school meals https://www.compare-school-performance.service.gov.uk/school/137157/the-london-oratory-school/absence-and-pupil-population - the national average is 27%, and in other schools in the borough it's as high as 40%
