For example, one of the questions asked is "did you pack your own suitcase?"
They aren't going to search your suitcase because of your race. That would be bad. It is bad not because of touchy feely reasons but rather because it isn't optimally effective.
They search based on a far more sophisticated probabilistic threat model based on real world data. All the questions and the way they are asked have logic behind them. It works.
Does that answer your indignation noises?
How you justify racial profiling, only show that you are completely clueless to what it's like being racially profiled ALL the time.
It sounds like you are under the impression that people are being inconvenienced simply out of spite or due to the discretion of some unfriendly TSA-type airport employee - nope. Understandable why you would perceive things as such but the reality is very different, there is quite a lot going on, before you even board the plane, that you don't see. Places where it really matters, like Israel, cannot afford to engage in security theatre, it is all derived by logic.
How it works as is explained in great detail in this video: https://www.youtube.com/watch?v=1Y1kJpHBn50
Appeals to emotion mean nothing to me. I get that it feels bad and don't particularly care as being blown up feels worse, promise. If after watching that you have pragmatic improvements to suggest I am all ears. It completely addresses your point, in fact it even explains how this approach probably doesn't scale to larger airports/other-countries.
