Dear wsieber:

I just meant that if you began a sentence with: "I demand that..." with the following bit of information including that the person in question should be acquitted, that it would not be considered unusual to follow it with "she be acquitted."

Let's say something more ordinary:

I insist that he be informed.
And Fish's alteration works well here: I insist that he should be informed.

I think we hear this type of construction, but I don't demand that it be used. And I don't insist that it be used. And I don't make a motion that it be used. I just think it's used pretty regularly and that there are many other ways to express meaning without using the construction. Such is the flexibility of the language.

Ain't English just grand? And I don't demand that it be limited to a highly restricted group of constructions!

[Beware: If you say something often enough, it will begin to appear to be completely incorrect!]

Best regards,
WW
