I keep getting emails from some petition site or another after signing something there, begging me to sign various petitions. I always got kinda tired of it, because (along with the spam issues) you're asking random everyday people to take an opinion on a subject they know nothing about.
One that I got yesterday was a petition to stop funding the F-35 Lightning II. Who the HELL is going to understand the capabilities of that fighter, its cost compared to everything else, whether or not it's proper for modern warfare, and the politics behind its creation and the demands to shut it down? This is a complex issue that a ton of people don't give two shits about, and you're trying to get random folks to back you up?
