Ever felt so strongly about something so much you decided to stick with it until such a point where something (or someone) eventually gave out? Maybe it's political, maybe it's a feud with a long standing rival, maybe you're standing up for others who either can't or won't stand up for themselves, maybe you feel compelled to protect something you love that's ultimately doomed to expire, perhaps you have a different reason entirely.

When have you stood for/with something til the bitter end? What could drive you to it in the future?
