Should I use "it" or "they" in the following statement?
Let's bring down the government.
It doesn't speak for us!
They don't speak for us!
Either would work, I think. You can interpret the word government to mean the abstract, fictitious entity that people refer to as "the government" or you can read it more literally to mean something like "the people who govern us."
In this context most people would say "it" instead of "they," though. It seems to correspond better, on paper, at least.
