Yeah, just like eating a lot doesn't make you a gourmand if all you're eating is McDonald's, reading a lot doesn't make you intellectual if all you're reading is mindless pulp.

For instance, watching Cosmos is probably a more intellectual pursuit than reading Twilight.

The other real problem is that even that pulp can sometimes have value above the material itself. Sometimes, even the most mass-marketed media can propose decent hypothetical questions and give cause for self-reflection.
