"That is complete nonsense."
Yes it is, and old nonsense. The accusation that women become pregnant to obtain benefits has been the cry of every religious fudamentalist throughout my life.
It has also been reguarly used by the Conservative right to undermine the benefits system for as long as I can remember with crass statements like "We must think very carefully before abandoning all responsibility for our actions".
Abortion is a complicated issue and it really time the dinosaurs among us begin to come to terms with those complications and stop making peoples lives a misery at a time when they are at their weakest and most vunerable.
