While substance abuse causes all kinds of problems, particularly for children, it is obvious (to me at least) that this measure exploits vulnerability to drive a savage eugenics agenda. It bribes vulnerable people into handing over their fertility in return for a quick fix, promotes a ring-fence of prejudice and sin-construction around drug users, and simplifies human beings into "addicts" and "normals".
Project Prevention's website states that its primary aim is awareness-raising (couldn't they just hand out some fliers or something), and its secondary aim is to "reduce the burden of this social problem on taxpayers". Sterilisation programmes are clearly not publicity-driven, so it is fair to assume that one of the main drives behind this project, once society has been divided up into "addicts" and "normals", is to remove the "addicts" from society and the gene pool, and leave the "normals" a bit more well off. Isn't that nice.
What can we do to make sure this foul stench blows well clear of UK?
