What are some forms of “art” that some people do not consider to be art?

Porn is more like an extreme sport...from what I hear.

I would certainly not consider most of  the graffiti we see, as art - illiterate scrawls, obscenities etc sprayed on others' property for the sheer hell of it. Those examples are cheap, tawdry, antisocial, criminal damage carried out by people who choose to be tawdry, antisocial vandals.

A graffito that genuinely is a product of artistic skill, and entirely with the property owner's permission, is a different matter and one I would consider artistic. Some  examples are very clever, such as those pavement drawings in pastels that appear to show a huge hole in the ground. 

Besides that, how does one define "art"? Not by a list like that.

It shows mere dislikes with no reference to any assessments of technical skill or aesthetic depth; and some of those examples reveal ignorance as well as simple dislike.


It's a bit like those empty questions asking things like "Which was the best band ever?" - collating the answers creates merely equally empty, random lists of bands and song-&-dance troupes that are not bands. 

A really smeary painted canvas (maybe only couple or few colors), that’s probably called just a simple abstract, which I may not like it that much for an example.
