If I had a platform that millions of people listened to (which I don’t), and strongly held beliefs about how the country could be made better for everyone (which I do), why wouldn’t I use my platform to share those beliefs? How could I not?

No one MUST obey what either of them says, just like no one would be compelled to obey me in my hypothetical. But I don’t really have a problem with any person using whatever platform they’ve found themselves with to express their own beliefs and desires. I don’t think people lose the right to free expression just because they are rich and/or famous and/or powerful.

Edit: And if you piss a lot of people off and lose all your advertisers because your opinions are repugnant and awful - well hey, that’s the choice you made.
