I believe you're exaggerating a bit. That being said it would help if the person who posted this was more specific on how intelligent that he believes they should be. I don't think it should be in a ghouls prerogative to find a husband/wife/girlfriend/boyfriend, go through the trouble of getting a draught, and have a family with a kid or 2. That's unreasonable in my mind and that level of intelligence in an undead creature should not be present nor should they even be capable of a relationship or having friends besides other beings like it.
