Just noting the existence of a trend, not making any broader statement about redditors being representative of the population. Hopefully we can at least agree there are millennials on Reddit upvoting the style, or if not there’s always plenty of articles like https://millennialmagazine.com/2019/10/02/why-are-millennial.... Or, if that isn’t compelling either, there are replies from other millennials here indicating they like it.

In any case try not to worry too much about it, there are plenty of people with (arguably) bad taste in every generation.
