I think the guardians of the galaxy are pretty crap films so I don't really care who gets fired from them. From what I read about the situation it says some internet trolls dug up the tweets from ages ago, Firing him seems harsh assuming he hasn't done any other weird things that point to him actually committing a sexual offense or something, I'd probably care if I liked the films or knew who this man was.
Are you ready for the fire? We are firemen. WE ARE FIREMEN! The heat doesn’t bother us. We live in the heat. We train in the heat. It tells us that we’re ready, we’re at home, we’re where we’re supposed to be. Flames don’t intimidate us. What do we do? We control the flame. We control them. We move the flames where we want to. And then we extinguish them.
Impersonation is treason.
