This commerical by Amazon can be found here: https://youtu.be/7RJ7-zSxuqk

Various children respond "here" to roll call by their teacher in regard to what they want to be when they grow up.

Two previous children respond  "here" to paleontologist and zoologist. However the only black child in the commerical responds "here" to "Rainbow Unicorn Trainer" which isn't a real job. 

Whether intentional or not this clip is in bad taste and demoralizing in that it encourages a person of color to be much like the unicorn "invisible" and a non-contributing member of society.  

Our hope is for an apology to be issued by Amazon and for the commercial's removal.
