I personally reckon that even if you did try to phone a radio station the chances of you getting put on air are probably zero. Lets face it, you don't just phone in and it gets answered at the other end by the dj. It will be answered by a secretary who will probably do his/her best to be rid of you as soon as possible. They don't want to have that sort of subject being discussed on their stations. It wouldn't do them any publicity favours what so ever.

And that is if you do phone, which I wouldn't recommend any way. It just ain't the right sort of environment to be talking about subject areas like that.
