This answer asserts that a soap dispenser that does not work properly for a black person was designed by white people who design products for white people without concern for other races. There is no evidence that this assertion of race is correct, much less that the designers have this view of race. Alternative explanations for the dispenser's dysfunction and other likely make ups of the team's race can be found in the chat linked in the comments.
This content is nothing more than the application of a racial stereotype of white people. As such, it is clearly a violation of the "No bigotry" clause of Code of Conduct:
We don’t tolerate any language likely to offend or alienate people based on race, gender, sexual orientation, or religion — and those are just a few examples. When in doubt, just don’t.
Moderators have already intervened in this post's comment chain. They have already seen that the claim generated controversy, offense, and alienation. They moved the controversy to chat once. (That I understand; it's standard policy when debates ensue.) Comments were deleted again later as people continued to debate the content.
What I don't understand is this: why did moderators do nothing about this inappropriate content in the post? I was about to flag it, but to be quite frank, I'm a little angry that this kind of content has been sitting here so long when it's clearly against policy and moderators clearly knew it was a problem. I would like some explanation of why they didn't intervene.
