If you work in or around the technology industry, specifically the software industry, more specifically the US tech industry (although the entire Western World is heading the same way, as far as I can tell) you should look at this web site, and seriously consider signing the pledge. It's short and you should of course read and understand it yourself, but in summary it says "I will quit before I will help build a Muslim registry database or anything similar." I honestly cannot see any reason not to at least agree with the idea.
You may reasonably elect to not sign on other grounds, of course, but to be blunt, if you disagree with the general thrust of the pledge, you are wrong.
