Whether in a given area this is achieved by having a school using cp and one not, or whether by individual opt-out doesn’t matter. So long as a standard provision exists without loopholes we are fine. this gets rid of the inherent sexism of boys v girls etc ………there is no group mandate because there is no need for one. You approve of your child being beaten – we can accommodate you: and vice versa? We can as well.
That deals with the issue of choice at an individual level.
My objections to CP are different of course.
