Quite clearly the 'enemy' is anyone who aims to ignore the climate crisis in order to continue living as before. This would include all of the fossil fuel industry and the governments that support them. And yes it is a fight when those same fossil fuel industries continue to increase their output of CO2 and methane, no matter how much they are asked to stop. Fighting is the last resort and we are left with the last resort after all these decades of being ignored. When someone invades your land and destroys all you have, you have every right to call them your enemy and fight them with all your will.
Stop making excuses for the industries that are slowly choking you to death and increasing their grip with every passing day.
