If just a few people who have never come to terms or heard the ideas before have engaged with it where they otherwise wouldn't have, especially if they come to the comments ready to give a reactionary piece of their mind and see the discssion, then I think the shock value strategy worked. It's ultimately the creator's choice how they present it, and I see the value in being evocative. If the title were "How Heirarchical Social Systems Contribute to Anthropogenic Climate Change," frankly it just wouldn't get the exposure. As marketing, politcal discourse, and everyday experience will attest to, appeal to emotion works.
