The entire thing about the wording was, to me, deliberately designed for one reason and one reason only. To stave off the claims that the ballot paper was unfair to either of the groups.
The more words, the more people have to read, the more likely the wrong result will be produced.
Even the wording is archaic. I can just see me saying to my Grandchildren "I want you to Remain here". Yes, likely. We use Stay in almost all circumstances. Remain, remains, remaining are used in places where stay won't work. Just look at
this link. We don't use remain in our vocabulary unless stay is not the correct term and this was in books. Books retain older words ten times longer than the spoken vocabulary.
Just think about how you use the language. When it is finished only that will Remain. When he is finished he will Stay there until I come. Using remain in the first context is correct and stay is totally wrong. You can use remain in the second context but we normally use stay. People with less vocabulary will use stay and not remain.
To me, using remain where stay works is not using the common vocabulary. In this instance that is not what should be done.
I put it in my last post.
Today Britain is a member of the EU; do you want to:
Leave
Stay.
Absolutely brass tacks, simple, virtually no words, using the words and vocabulary that is used on a daily basis.
Anything else is words for no purpose. Or words to excuse actions. Go re-read the wordy BS in the proposed ballot paper and then read what I have just written. Why put any more in there?
