"The bias towards tallness is one of society's most blatant and forgiven prejudices." - John Kenneth Galbraith
Never Go Full Retard
Deep down they know the weight/height thing is a double standard, so they decided to go all in with the fallacy of relative privation, even though death wasn't the topic at hand. Allegedly, the red person is a feminist so that makes this extra funny. Many people of this type claim to care about wage gaps and mental health, which height affects, and of course they care about "body shaming," but only in regards to female weight.
Feminists who don't take height prejudice seriously are doing women a disfavor, as it's been shown that a tall woman is treated the same as a tall man at work. It just so happens that women are shorter on average. They need to realize that in an alternate reality where women are taller and stronger on average than men, sexism would be flipped around. The importance of how humans perceive size cannot be stated enough.
P.S. Men statistically die more than women anyway.
