Well, they used the line "vulnerabilities and exploits" in Violet Blue's abstract to suggest that the talk would be about how to exploit vulnerable people (Seriously? For a phrase that is THAT common in security circles?).

Even if that had been the topic of her talk, we all know that the best way to defend against an exploit is to just keep it a secret and hope that no one else knows about it.

Fixed. The talk was actually being given by a woman, and according to her blog, the only mention of rape was a section on avoiding date rape drugs. So really, by blocking this talk, they kept rape prevention information out of the hands of potential victims.

And if you read the science fiction novels depicting life on the planet Arrakis, you'll find that people can rapidly travel through space and see the future by doing drugs. There are also enormous worms that live in the desert and produce said drugs. Some people have also developed an economy based on water. There is a quasi religious order who has an intricate breeding program and can control all of their bodily functions. Sci fi is so crazy, right?

(PS, I am unfamiliar with "Libertopia", but it sounds like something Stephen Colbert would make up.)

As a resident of Tucson, this is alarming. If I lived farther north I'd be used to it, as Sheriff Arpaio has already made Phoenix a Fourth Amendment Free Zone.

The FDA is making it increasingly hard for companies to label product as NOT having GMOs as well (Source).

Newsflash: Millions of people are going to starve to death with or without GMO crops. It's not like Monsanto or ADM is just going to magnanimously ship all this extra food to Africa out of the goodness of their hearts. Producing more food does absolutely nothing to ensure that the surplus actually gets to the people who need it. One study claims that 40% of food in the US goes to waste (Link). A good chunk of this hypothetical extra GM food will probably just add to that.
