I'm really bummed out by the cast response to this incident. It's actually worse for me than Gunn getting fired. What the people behind outrages like this one are managing to do is discover a new kind of censorship, one that is created by a few but then spread by the masses, without even realizing it. People join the outrage thinking they're doing something good and in, I assume, good faith, but they're just being used as pawns.
The cast's response has been so vague and free of any concrete emotion towards James that it shows me that they're all scared, scared of saying something that might cost them their job or fandom. It's plain censorship and psychological abuse through social media. And it will only grow from here, famous people will start deleting past jokes, then accounts (like Harmon just did), then stop saying what goes through their minds altogether. Should they always say what goes through their minds? No. But they should have the right to do it.
Where I'm from we're lead to believe that there are no limits to humor and everything goes. Of course this leads to some vary bad jokes and many offensive ones, but they're not evil in their core. And I would never think badly of the humorists themselves for the jokes they do.
Firing him on the basis of 6 year-old tweets shows me Disney has no backbone and that there's no emotion when it comes to franchise movie-making. They can show us photos of all the MCU cast looking jolly for the 10y celebration, but in the end they're all disposable. It also removes the right to grow as people from these artists (you're always growing as a person and individual, whether you're 8 or 80) and the right to experimentation and free speech.
And then you have the president of the USA straight out threatening another country on twitter and it's fair game.
Oh well, at the end of the day there are much worse things happening in the world than James Gunn being fired, and I'm not even a big fan of the guy (as a director), it's just a minor thing that to me means that the dark times can only get darker.
