Your argument originally was what you do in your off time should not be tied back to your work. You should not be fired for things you do in your free time. You are free to be racist, sexist, or bigoted in the United States. Its a part of freedom of speech in the US. You can even be a Nazi, which can be considered a political affiliation. But people get fired for such stuff all the time. Why? Because companies don't want to be branded as such. They don't want to be the Nazi sympathizers or the company who employs the guy who sent around a memo about how women are inferior and here is the "scientific" prove. This is exactly why James Gunn got fired for joking about raping children. Because Disney doesn't want to be the place that employs the guy who thinks pedophile is funny to make family films.
And this is exactly why I think it is a very bad argument to suggest one cannot be fired for what they do while off the clock. Because while plenty of things are protected in that regard and should be, rightly, not everything is.
Also I don't think it is a different conversation, but few people just say they are racist without justification, or that they are in fact racist or bigoted at all. A big part of Trump's bigotry comes with his policies. And people support his racist and sexist policies, while claiming to be none of those things.
