Argumentum ad Boomerum
A very common modern informal fallacy. Most often it's an argumentation of the older generation (but also used by other generations) against anything remotely modern: pop culture, social media, technology and/or internet. This type of argumentation comes from Baby Boomer Generation, hence the name.
