I’m all for discussing media-frenzy, but there is absolutely no way your tweet was to be the waning catalyst for people’s eventual outrage (not to mention your follower-audience is in no way reflective of a vast online society). If not you, one of the thousands of other people poking their head into Sephora stores loaded with smartphones would have eventually seen it. The media built this story off a morally-contentious lipstick color and an affiliated celebrity.
There is some brutal irony (bordering on hypocrisy) in getting people riled up about this perceived appropriation of your non-issue tweet. In reality this is just one of the never ending pseudo-offenses where a retailer does something questionable and everyone ends up talking about it, which I agree is annoying and disingenuously causing commotion (see: cable news). All of the publication you’ve mentioned have demographics stretching far beyond Upworthy clickbait lovers. Have you ever considered that conservative parents might stumble onto the topic on something like Time.com and find it salient to their world views (e.g. they are offended)? It is not manufactured outrage. It is harvested outrage. Born from seeds in the hearts of people who don’t share your norms (nor mine).
