If you meant absoutely nothing about them being racist, why would you even show the photos, and comment about there being primarily white people, and that more of them are fat? It's because you're subtly implying that they're racist, fat, uneducated, etc. Spare us the lies. If you weren't implying they were racist then why even post the pictures and make those ignorant comments? See, DP tends to comprise more on average those people who are intelligent, who can understand things a bit more clearly, and who also practice an unimportant concept called critical thinking.
You're making smarmy insinuations of them being racist, and now you're so intellectually dishonest that you won't even acknowledge what you're doing. If you don't think they're racist/fat/ignorant, then don't make cowardly comments about their skin color, their weight, or what you assume they listen to. Understood?
