If I was? Or if I were?

Språkdiskussionen i hemmet lät inte vänta på sig.
Språkpolis ett och två var den här gången överens.
I was
You were
osv osv osv

Jag googlar eller gogglar som man också kan reta språkpoliser med. Fast den bästa är när jag säger jag gogglar det på youtube, då goggla egentligen står för ordet sök.

Det här säger google:
"Both of them are correct in relaxed speech, but IF I WERE YOU is to be used in an essay (along with the formal forms like IT IS I, IT WAS WE/SHE, HE IS TALLER THAN I)

The same is true with I WISH:

I wish I was you (informal, spoken).
I wish I were you (formal, written).


I wish she was here (informal, spoken).
I wish she were here (formal, written).

Both 'IF I WAS YOU' and 'IT'S ME' are considered inelegant/incorrect, by normative grammarians, but are perfectly acceptable in colloquial language."
