This song is about standing up for one's beliefs in society. It's tough to speak up against those in power and would be safer if we didn't ("We don't bleed when we don't fight") but if we don't fight we're going to lose what we have; if you throw your arms in the air (give up) we'll lose our shirts in the fire. He doesn't enjoy getting beat down by his fight but it's important and he wants you to join him and stop letting things get worse around you, because you're afraid.
