No. That is what you claim, but you have been unable to prove or offer any meaningful argument to support.

They cancelled the contract because it has already impacting rates and sales. TV-Network shows is a highly competitive market. With plenty of them being cancelled. For example, The Expanse, a great show with a decent following is going to be cancel. And the people on that show don't go around playing the victim for that, they are grateful for the opportunity.

Employment is for the people who is willing to do the job. The full job, not just the parts they like. And part of an actor's job is to be liked. For a Disney actor, it also mean doing promotions, selling merchandise and the brand. What they say impacts the brand and using Disney platform to promote her political ideas while hitting their bottom line is a Big NO.

Considering that in the cases of Bree Larson and Chris Pratt Marvel didn't fire them, I would say that it is clear that Marvel has no problem with free speech (Except in China), but with losing money. But I guess that you expected special treatment for Gina Carano or something. By the way, I'm still waiting for you to defend the free speech of people on the left, or feminist or LGTBI people. There are plenty of times where they are attacked for expressing their opinions. Prove me wrong, go to the alt-right forums and defend their freedom of speech. XD
