That depends on if you are dealing with someone who distinguishes between "I am physically incapable of assuming and holding the position" and "I am physically able but I choose not to assume the position".

Of course, the only reason such a distinction ever existed in the first place is because TSA sought to punish those who 'opt out' with retaliation and delay while avoiding the embarrassment of harassing John McCain (or other war casualties) because they are physically unable to perform.

IME, many TSOs refuse to acknowledge the difference between 'can not' and 'will not'. PHX T2 TSOs and supervisors are particularly adamant: when you point out that you have a physical limitation that prevents you from complying with their order, they get right in your face and repeat, loudly, "then you are an opt-out".

They must have been trained to speak very loudly, so loudly that sometime the spittle flies (not a good look). I'm sure they don't do it to be demeaning to the pax; some overpaid trainer probably assured them that anyone who balks at the NoS must be hard of hearing or have language comprehension issues, both of which are best addressed by speaking loudly (and wetly).
