Is genocide not the most serious subject that infographic brings up? It's not some minor footnote in the infographic; it's right at the very top in the most prominent position. I'd say that infographic is more about genocide than anything else.
The graphic is about how each level is supported by the level beneath it.
Minor footnote is a straw man and false dichotomy. The graphic is about all the things like I said. It wouldn't be less about genocide if it was an escalating list. It isn't less about biased attitudes because it's a pyramid.
The infographic being substantially about genocide, albeit not exclusively about genocide, does not change how I feel about it's use in that conversation: a blatantly hostile escalation. When you send somebody this infographic to scold them, you are insinuating that their actions might lay a foundation for genocide. That message comes across loud and clear, and in the Basecamp context, was plainly over the line.
