It's kind of funny the way americans seem to think.
This apparently is racist as hell for them but they would do exactly the same with latinos/spanish speakers and "despacito" (and ofc they did, shit was funny and not offensive by any means). This shit isn't offensive at all, it's just ppl wanting to have a little laugh jesus.
This will only offensive if you actually lack of self-esteem. Stop playing the victim card, this will only hurt you in the long run, learn to take these things as meaningless and you will be happier
