We are talking about a trend. Trends don’t tell us about individuals, it only tells us about groups. There are lots of millenials who are just as you say, and we need every one of them.
Sadly, there seems to be more Millennials ( and they’re liberals or extreme lefties )who are like the ones in the article, than the other kind. On the bright side, the “TREND” ones aren’t reproducing, so there is that.
