thank you for correcting my facts the way a robot or autistic child would, but allow me to spell this out for you.
ignorance is not the same as factually incorrect. if i said to an obese woman "you are looking fat today," though correct, i would either be behaving purposely mean or ignorant to social norms.
similarly, someone telling another person [the people you love who have chosen to defend your country in war have done so needlessly] is ignorant to social norms.
since you are not american is it safe to assume you personally know zero american soldiers at war right now?
