I did contemplate fisking the fucker, but Bishop Hill has done such a fine job that any effort by your humble Devil seems superfluous. Here's a sample...
Collectively, as a society, we have a responsibility to our children - who are not the property of their parents and shouldn’t be treated as such.
And they are the property of "society" are they? You clearly think so. But if you took the trouble to check it out, you would find that children are legally the responsibility of parents. This is why it is not possible to sue the state when your teenagers take to drugs. Are you advocating that this should be possible? Of course not. When you say that children are the "responsibility of society" you don't mean anything of the sort. You are simply demanding a right to indoctrinate them to your personal preferences while avoiding any actual responsibility. It's the same as every other time you deal with the state—interfering busybodies get to tell you what to do but take no responsibility for the outcome. Teachers are not responsible for delivering a shitty education, child welfare officers are not responsible when children die. As soon as the state starts ruining the lives of home educated children they will not be responsible for that either.
Do go and have a read; amongst other things, His Ecclesiastical Eminence manages to link to actual evidence which David Semple—for all his wittering on about "the scientific method, skepticism [sic] and all forms of rational argument and the examination of evidence"—seems unable to cite. The cunt.
