I'm going to invoke Goodwins law here, by mentioning Nazi's.
The European Convention for Human Rights was drafted to ensure that a Nazi Germany situation should never occur again. Eventually through treaty, negotiation, wheeling and dealing it became law in the UK.
The ECHR covers such simple ideas as the right not to be murdered by individual or state. Not to be persecuted for your religious beliefs, or lack thereof. The right to have a family. The right not to be worked so hard you are effectively a slave. The right to own property.
I'm not Jewish, but having studied at college/uni in a Jewish are, then working for 20 years for companies in the same area, the vast majority of my friends are. Each year many of my friends attend memorial services, visit concentration camps or partake in some act of rememberance, for family members that were either killed by the state, persecuted for their beliefs, torn away from their families or simply had their property taken away and left destitute. It happens frequently enough that it also affects me, a gentile, to see my friends having to go through this.
It disturbs me greatly, that there seems to be a gaining movement to remove us from this safeguard. I'm aware of the differences between the EU, EC, European Court, European Convention for Human Rights, but it stresses me out that so many people, are not. They see "Europe" as some bad force stopping us from deporting or locking up some really nasty people, whilst forgetting what did happen when such laws Europe provides didn't exist. I also find it disturbing that muslims are increasingly becoming the new jews in terms of intollerance and derision, especially in the media which tries to whip up public hatred, that is then used to justify leaving Europe.
Regrettably I think that us leaving the EU is inevitable, there's just too much anger at the moment for us to stay. And once we leave one part of Europe, all the other parts will be left one by one when Joe Public is instructed by the media that we're still subject to some treaty, agreement or law.
I don't know the answer, but I see regularly the effects of what did happen last time round.
