Some of the worst kinds of people are those who think they're so smart when they aren't.

Your comments take everything out of context, as if you have no idea where she was, what the Gala was for, the rare tradition of making a political statement with a dress, and so much more about the context. If you wore the dress, would that be an argument? Not really, because you're an anonymous online person. It's a slogan if you wear it.

If a politician wears that dress in a room of rich people, that is an argument. Do you understand?

The person, the dress, the statement on the expensive dress, the rich people at the Gala, the publicity for it, the history of political statements at Galas, the fact that this is a fundraiser, the need for rich people to pay a fair share of taxes (which some rich people agree with), and so much more make this 'event' of her's and the dress at the Gala an argument.

And you are definitely in no position to determine who has "brains" and who doesn't. If you were a zombie, you'd starve.
