Also, women are not children. Children deserve protection because they don't know any better, their minds are not fully equipped to understand what going to war means. Additionally, children make very poor soldiers, as their motor skills and reasoning skills and emotional control are just not developed enough to function as well as an adult, particularly in times of extreme stress such as war.
So again, children require and deserve protection from the rest of society. Women neither require it, nor deserve it, not any more than any other civilian.
Misandry would be saying men must be sent to war instead of women because they are inferior, or because they deserve a worse life, or something like that.
World War 2 had a shitload of famous actors, athletes, politician's kids, etc go off to war. What are you smoking?
