We have a question How can I convince airport screeners to stop asking why I prefer pat-downs? which seems legit on the first look.
However, looking deeper we see that what the OP will to achieve (Stop asking for reason for avoiding airport screeners) is impossible because the security is (likely) instructed to make life hard to the people who make their life hard (refusing to use screener).
The OP doesn't give any logical reason for not wanting to airport screeners so it looks the only reason is 'no because no' which is, honestly, childish.
Should the answer to such question be that OP should stop behave childish, and all the problems will perish? Or vote to close because no valid reason for such behavior was given? Or the question is OK I'm just picky?
