This is exactly the trouble with #nodebate.
Transactivists, which I consider Mr Cohen to be, have created silos around themselves and they have therefore not developed their case beyond "I want".
It doesn't work. Adults debate issues, toddlers and teens say "I want".
The reason the Times comments are so dire is not because of Mumsnet, but rather because the majority of people share the views of people on MN because people on MN are just people. Mainly female people, but, they are people too.
Some of us are quite smart, stick around, Ben, it's an interesting place.
