You're making two mistakes here. One, you're assuming that all TSA agents are evil jerks who only took the job so they can fulfill their life's goal of fucking with coldpie. I'll counter that the vast majority of TSA employees are regular people like you'd find in any entry level position. Maybe they hate their job, or maybe they feel they are doing their part in keeping America safe (whether they believe the security theater bullshit they're fed, or not). Either way, they are human beings just like you. You are no better than they are, and vice versa. You are putting yourself on a pedestal and looking down on them as if they are subhuman. That is textbook sociopath.
Two, you are equating policy set by their superiors with the entry level agents themselves. They have absolutely no say in what they are forced to do, yet they are the ones you're taking it all out on. You're quite simply barking up the wrong tree.
If you want anyone to take you seriously rather than thinking you're a raving lunatic, you should direct your ire towards the policy makers. Work the political angle, because you're fighting a losing battle on the ground. Making one of thousands of employees feel like shit does absolutely nothing for your claimed cause, and only serves to feed your own selfish need to feel superior (which I strongly suspect is your actual motive, whether you realize it or not).
