It's an opinion on the WORD millennial with this implied, angsty attitude towards the perceived marginalization of his (and my) generation. He doesn't have a problem with the word, he has a problem with popular culture's perception of millennials. Do you want to be called Baby Boomers? Generation X? These are meaningless tags so we don't have to say Born: 1920-1940, Born 1940-1960, etc. He may as well complain about why we name hurricanes in alphabetical order. I just don't view this as productive: it's not a discussion of WHY we are perceived this way and what this informs us about generational differences - it's the author complaining about how people complain about him.
If I had a plethora (reference intended) of badges to give, which I don't, I would badge this comment.
I don't think that's a fair argument. The word exists. Why does it exist? Isn't it natural to ask questions about why we agree on certain labels? What purpose do they serve? I find myself thinking about this a lot, especially because the word is thrown around so liberally on the Internet. It's not productive to question the nature of words? Kierkegaard said something like, "to label me is to negate me." To be fair, I only know that quote from Wayne's World, but I think it applies nonetheless.
