Spielman's speech is interesting and relevant to its context of Ofsted and Stonewall.
I picked up a sense that Spielman anticipates that it's society that will change on this rather than grappling with the conflict between individual and wider rights. I may be wrong. For me, it has echoes with the statements of Human Rights lawyers who acknowledge that there are fundamental conflicts between rights for individuals that have irreconcilable consequences for others (Canada comes to mind).
I confess to a bout of 'whatabouttery' while reading Spielman's speech. I was strongly reminded about responding to the consultation about RSE in the context of the number of sexual assaults in our school system and the many threads here about those assaults and how little has changed in our school system over the decades.
Possibly a personal knee-jerk and something to which I should give more consideration.
