It is not disingenuous as nothing underhand I am down right cynical though.
More chance of falling out the shower and banging your head seriously than you have in airsoft. So when someone tells me they wear one because they play cqb I am going to snort and have a derisive dig.
Personal choice but in no way necessary and most of the cheap airsoft repros are probably more damaging than good. See a few break sharply when knocked.
I will just put my faith in not being a clumsy fucker.
(Actually looking back on my list of injuries that might be a bad idea)
