Is it wrong to judge how people behaved in the past based on today's morals?

So you do insist on making the choice for your own body when it comes to going through airport security?  You don't feel like going through all of that on a particular day, or you don't want to be patted down or whatever, and you say, "I insist on making the choice for my own body, and I'm not choosing for you to do this to me today.  Who are you to tell me what I can and can't do with my own body?  I'm not going through this security rigamarole, and I'm walking back to my gate and getting on my plane whenever I feel like getting on my plane."
