Two is enough to invalidate the assumption I think Oligopsony made, but in any case what's true "statistically speaking" is relevant only to those who are statistically fairly typical. LW is full of people who are, in various ways, unusual, and there is some reason to think that quite a few LW participants have unconventional political opinions. (And Oligopsony was specifically addressing the less-conventional, I think; hence "assuming your politics aren't so unbelievably unimaginative ...".)
