what would be cool is irrelevant.
What matters is that we fight. names only serve to distinguish between similar things. What matters is that we are alive, and they should be dead.
Since the zombies started, it no longer matters. Now,m every woman, child, man and senior is a fighter. we all fight against one common enemy.
As far as I go, it would be best to leave the resistance without name. A name is a symbol, and I leave symbols to the simple-minded.
resistance or survivors. why come up with anything more complicated? unless ur totally bored and want to make something like S.U.R.V.I.V.O.R.S. which would stand for something. but if you do, you dont deserve to live. and it wont catch on.
