> What is the controversial opinion you’re actually worried about expressing at work? The controversial opinion that free speech should apply to workplaces. Yes lots of people oppose free speech. Some of those people might be willing to fire people over it.
I don't believe you that normal people would fire an employee for saying "free speech should apply to workplaces." I believe there's some other idea that you're talking about expressing and then defending by saying "free speech should apply to workplaces." What is that idea?
Just because you wouldn't fire someone doesn't mean someone else wouldn't.
And free speech is a controversial opinion these days, depending on where you live.
