I'm pretty sure it's "when we choose to forget them" not "when we choose to forgive them". It could be either, but forget is what it sounds like and makes my interpretation of the song a lot stronger so I'm gonna go with it.
The song is saying that once you stop caring what people think about you (forget them) you can do anything. When you stop caring what people think people who are still self conscious will not understand because you will be able to say/do whatever you want while other people are hostages to their own self conscious worries (the day the hostages start making demands). The song becomes a tragedy when the speaker starts to believe what his lover says about him (but I believed you when you said I was ruined) and that destroys him and makes him a hostage to his self consciousness again. At the end of the song, 'you' (the speaker's lover) is all that's left of 'us' because the speaker has been destroyed by self consciousness.
