it is a good thought. hits deep as well. though, i found it a bit troubling the rejection of one's roots because exalting the past could put less emphasis on the present or the future. i don't think that is universal; partly an erasure mindset. but i understand it in context of the article.
I find that it makes sense as a warning not mythologize your roots. It could even be defended that looking for one's root is indistinguishable from mythologizing. It can be a powerful political tool but ultimately it belongs to those most skilled into making it say what they want.
