It's a snip!

There are representatives of an American charity going round London offering £200 to any drug addict who agrees to be sterilised.  The logic (if you can call it that) appears to be that such people are unfit to become parents, and the charity is therefore preventing the putative future abuse of the children these addicts might otherwise have.  It's certainly true that you can look at some families and say "these people should never have been allowed to have children" but identifying such people in advance is an entirely different matter, and doing so by categorisation smacks horribly of the Nazi "untermensch" philosophy.
