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?
Good thing that none of my friends went, your friends do not have to go either.
