The fact that they're considered "persons" and not property, akin to pet animals.
One may say this is a problem with society, not with the foids themselves. Fair enough.
What annoys me most about foids is their lack of any self-awareness (permanent childish narcissism) consequently they lack any sense of truth, justice, or beauty. From this psychological defect flows all of their annoying behaviors and insufferable instrumentalization of language as a means of deceit and manipulation.
Nietzsche and Schopenhauer were right about women.
