That reads to me as an atheist statement, yet C.S. Lewis was a Christian apologist according to https://en.wikipedia.org/wiki/C._S._Lewis
Lewis, to the best of my knowledge (and I've read most of his works), didn't invest much time in political activism—much as Jesus was content to pay the Roman soldiers his taxes due and return to teaching.
(I'm a bit of a politico, myself, but it's just a hobby. Or my Malcolm Reynolds side coming out. I don't mistake it for my faith. Bush and Obama are both equally bad news in my book.)
Words can have different meanings depending on context, that's normal, but just like when we're writing software, we have to establish the context before we'll get anywhere.
