Hey, I read through some replies of OP but I'm still not convinced with "it" referring to the war. From the author's perspective is it the War that's "unjust" or is it the action of paying taxes, which indirectly makes the author support the War, "unjust"?
Thank you
Thoreau did not pay taxes supporting the Mexican-American War because he felt it was unjust.
What can "it" refer to? Either war or taxes. But since 'taxes' is plural, 'it' cannot refer to taxes. Hence 'it' must refer to war.
Note that 'it' cannot refer to the action of paying taxes here. In that case, we would need to say something like:
He found it unjust that citizens were required to pay taxes supporting the war..
(the anticipatory it)
You need to give the clause that 'it' introduces. What did he find unjust? He found 'it' unjust. 'It' is the 'that clause' - 'that citizens were required to pay taxes supporting the war'
