Those who choose to jack in should really desist in calling folk who choose to attend. It's a cuntish thing to do.
I fully respect anyone's decision to jack it in. It is after all your own choice. Resignation letters etc. are a fucking embarrassment. If you don't want to go then DON'T FUCKING GO. What makes folk like this think they need to justify their own actions?
The only thing that will bring effective change today is exactly the same as what would have brought effective change in the mid 70's onwards. Just stop going - but sadly that isn't going to happen.
