I think fat men are (for the most part) aware of what disgusting pieces of shit they are.  They don't have expectations of some glorious bearer of perfect vagina showing up at their door step.  They are often shy, pathetic lumps waddling through public spaces with their face down low.  This starts at childhood where adolescent boys are not very accepting in general. While I hate them just as much, I believe that generally they know their place. Fat women on the other hand, especially in the past few years, feel they are members of the same species as we shitlords.  And in fact, often times also look down upon fat men.  They are often coddled by the majority of the other women in their life, told they are beautiful by well meaning yet idiotic others.  They are welcomed into the same social circles as human women, and often idiotic human males may even engage them for a late night desperation poke.. in short, they do not know their place. TL;DR - While I think the message should resonate for all fats,  I think the author decided that fat women need to actually be specifically called out so to be aware it does apply to them as well.
