I can never get used to seeing this response on otherwise normal OKCupid profiles.
It's insane how many people apparently believe in the general principles of eugenics, whether they realize it or not. Do these otherwise intelligent people not understand the implications of what they're saying? Do they really believe this, or do they just not give the question much thought? Are they reading it as "Would the world be better with fewer stupid people?" without thinking much about the means of accomplishing that?
Or maybe people are just terrible. Plenty of guys fail the rape questions too (e.g. "Is there any situation in which someone is obligated to have sex with you?").
