That's your opinion and I believe a mistaken one. Gilmore is one of the co-founders of the Electronic Frontier Foundation (EFF), an organization which is similar in ways to the Access Fund but which deals with cyberspace rather than a physical place.
Electronic Frontier Foundation--Defending Freedom in the Digital World
The Electronic Frontier Foundation (EFF) was created to defend our rights to think, speak, and share our ideas, thoughts, and needs using new technologies, such as the Internet and the World Wide Web. EFF is the first to identify threats to our basic rights online and to advocate on behalf of free expression in the digital age.
You might want to take a look at some of the current issues surrounding the use of the Internet, for example, some of the proposed legislation such as the Induce Act. Personally, I believe Gilmore is an advocate and is at the forefront of many pertinent issues regarding freedom of speech and other rights.
I honestly don't see why showing ID before boarding a plane is an invasion of my privacy. Likewise, I don't feel that my privacy has been invaded when I'm asked to sign a credit card reciept, either. What's the dude's problem?
I took a look at the EFF site, and it's interesting and necessary, but while I might agree with what the EFF's doing, I don't have to agree with this guy about the issue of presenting ID before boarding a plane. Totally different issues.
