The TSA is - objectively, by their own audits - complete security theater. Why bother to defend them, exactly?
Also, the spirit of the 4th Amendment is most certainly not "here, this is the easy way!" (yes, we are conducting mass surveillance but you can sort of opt out of one piece of it by going through a manual process over here that we will make you feel like you are burdening us by requesting)
correcting disinformation isn't defending something. do you want to live in a world where we dislike someone and so we just make up random terrible things about them that aren't true, and it's fine and encouraged because they're someone we dislike, and people aren't allowed to say "hey that's not actually true, at all"
