They do not use undocumented.  Check the stories.  If you find one that uses undocumented, let me know.

It's apparently accurate that the kid asked pointed (opinion word) questions.  It is NOT proven, other than Mom's sayso, that he was asked to leave the den because of those questions.  They didn't talk to the pack leadership, nor did they say they tried. He is still in the pack (packs are made up of numerous dens) which is an important fact omitted from the original.  

Excelling at political provocation (that post was removed) is a subjective opinion.  "Excelling" needs an objective measure to be a fact, and even then it's iffy - does a quarterback excel because of his rating? Compared to whom or what?. Even if you agree with an opinion, it doesn't make it an objective fact. Even if the subject of the opinion agrees with it, it's not a fact. Trump believes he excels at clearly expressing info but that doesn't make it a fact.  Facts are those things that are objectively true.
