Quite a lot of people feel that British law is being made in Brussells, that EU rights trump British rights, that non-British EU citizens in the UK get double the advantages so allowing a vote would be playing right into the hands of the "Out" campaign.
But quite a lot of people are also quite thick.
Yes. All euroskeptics are thick, it's true.
Not me that used the word "all" ...
Despite being in the "yes" camp myself, I have no problem with Eurosceptics who articulate sensible arguments. Personally I am much less pro-EU. However if the price of being "in Europe" is also being in the EU (a very interesting proposition that gets very little measured consideration) it's a price I would consider worth it. But I totally accept there are others who may not.
That's the 1% of intelligent debate covered.
The rest is mainly people parroting what they've heard from "a bloke", with zero input from their brain cells. These are the sort of people who think pulling out of the EU means an instant end to human rights (it doesn't. The UKs acceptance of the ECHR goes back to 1953. 20 years before we joined the EEC). Doubtless these are the same people who will trot out something -wrong- about straight bananas and metrication.
There's an old saying about fighting with pigs ... the thrust being that it's inadvisable as (a) you both get dirty and (b) the pig likes it. There's also a more up to date saying about arguing with idiots (a) you both end up discussing things which aren't true and (b) the idiot can always play the "Daily Mail says so" joker. Which as any fule nos is an antidote to actual facts.
At the time of the Maastrict treaty, I got chatting to a chap in his 70s. The radio reported the debate, and I casually mentioned something to the effect that the older generation were far less comfortable with the EC (as 'twas) than the youngsters. He then explained that he was fed up to the back teeth with the Tories feeling they had a monopoly on older folks opinions, and that he had voted Yes in '75 and would vote Yes again if ever asked. When I asked him why, he explained that he was made a PoW at Dunkirk, and spent 6 years in PoW camps, ending up in Poland. When the Nazis fell, he was hurriedly evacuated (marched over a thousand miles) and passed through Germany, Belgium and France, and lost count of the flattened towns and villages, and sheer human misery of innocents. As he said to me then, "if the EC is the price to pay to never see that again, then it's peace bought cheaply".
Any student of history will know that compared to any time in the past millennia, 1945-2015 has been one of the most peaceful in Europe's lifetime. You'd probably have to go back to the glory days of Rome to find an equivalent 70 year spell.
The world is settling into geo-political power blocs. We need to be in one.
