No idea why people hate White toilets so much, female nature is the same all over the world.
To me, White toilets have ugly faces but generally have beautiful bodies (fat in the right places), but their behaviour isn't too different from other toilets. They're less slutty than Noodlewhores and Sheboons and certainly less slutty than Turkwhores.
But I wouldn't even say that sluttiness is bad behaviour (non-slut toilets often shame sluts, but only because they lower every toilet's SMV).
White toilets have better standards because they have more valuable genes, everyone wants their children to reproduce and if you have a son who has more White genes he's more likely to reproduce.
