That's just an "Appeal to Popularity" fallacy.

Here's the consistent pattern of its use on UT:

1) An "Appeal to Popularity" fallacy is pronounced as if it carries great merit.
2) Amusement is expressed about those who disagree.
3) (optional) A stooge pops up up to attack those disagreeing with the fallacy; this is a pretext for the original proponent to roll his eyes and declare the discussion a waste of time.
4) Repeat whenever the fallacy is challenged.

That is about it.
