sp, i have seen similar polls which say that that it's more or less split down the middle,
as to it being a case if you are old you are against, if young then you are for. Someone had better tell the young bloke in today's paper, a committed Christian, he isn't in favour, neither i suspect are many young and old. I wish we wouldn't all get lumped together like this, if you haven't been asked how would anyone know.
In pretty much the same way they can't know for sure how many are pro Europe or anti, unless you have a countrywide referendum then you can't make that statement.
