Joss Whedon - you either love him or only like him a bit. I think it's probably impossible to hate Joss Whedon unless you're about 12 years old and have no sense of TV history.
Politically, Whedon is, of course, a great big feminist and Democrat, and you shouldn't be surprised that with a few exceptions - cough, cough, Sarah Michelle Gellar - so are his mates. With President Trump an actual realistic possibility in the next four months, Jossy-baby has got a huge number of his more famous pals to put together a video pleading with you not to vote for the racist, misogynist, homophobic, lying sociopathic conman who could well usher in the Apocalypse. He's even got half of the cast of The West Wing along for the ride.
The video's probably preaching to the converted and won't sway many dissenters, but it's worth a gander anyway because it's pretty funny, too.
