I personally think that anyone who steps outside of the bounds of civilised behavior (rapists, murderers etc) should forfeit their "Human Rights" and that the"Human Rights Act" is being used/ abused by certain sections of (in particular) the legal profession to acheive things that are not acceptable.
I do actually agree with what you say but I am just trying (probably badly) to illustrate the tightrope that you walk on when you try to treat everyone with an idealised fairness and equality.
If , for example, you think that it is fair that Muslim extremists are at liberty, in this country, to preach the downfall of western civilisation and to celebrate suicide bombers, because it would be impinging on there "Human Rights" to prevent them, then you must allow any legal political party to express their views as well, because, presumably it is their "Human Right" to be able to say whatever they like.
Sadly, in this country, in so many walks of life, we are no longer allowed to apply "Common Sense" solutions to problems. All IMHO.
