That is not the passive voice. The verb in that sentence is a copula. They’re entirely different, although they both use the verb to be. Maybe that’s how they are gotten confused.
I always thought a copula was a term in statistics for a multivariate cumulative distribution function, or possibly a domed structure on top of a roof (wait, that’s “cupola”!).
Notwithstanding your erudite correction, I maintain that there’s a passive element there (one might almost be inclined to describe it as “passive-aggressive”) which shares with the passive voice the desire to avoid accountability by characterizing some action or belief as essentially an unavoidable force of nature rather than a personal choice. For example, the Big Kahuna stating “effective next week your salaries will be reduced by 20%” instead of “I’m cutting your salaries by 20% next week (because I’m a greedy asshole)”. It fools no one but it makes the speaker appear less culpable.
Thank you for the kind invitation, but I think I’ll have to pass. While I have no appetite for the creation of an Academie Anglais (if you’ll pardon my neologism), I see the dumbing down of English in the matters of accepted conjugated forms and metaphorical idioms as an everyone problem.
There are plenty of things I read on the Dope that are nails on a chalkboard for me, so I understand where you’re coming from. But as Larry_Borgia said, it’s my problem that those things bother me, and it would be rude and selfish of me to point them out every time. I’m not asking you to get over them; I just ask why you need to point it out to everyone else.
Is your goal to teach the poster correct spelling and grammar? Then why not send a PM to the poster instead of interrupting the thread for everyone. And if it seems weird to send a PM to someone to correct their spelling, then maybe consider why you think it’s OK to post it publicly.
