Why can't East Asians write their wikipedia articles objectively?

Every time you read something about Korean history it reads like a nationalist with a weak grasp of English.

>Yushin attacked the Baekje capital, Sabi, in 660, in one of the most famous battles of that century, the Battle of Hwangsanbeol.


Dude I have never heard of that battle, or most Korean battles. You only think its famous because you're Korean and know little about the history of the entire rest of the world. And Korean history is optional in Korea, so most of you know shit and "learn" from watching Korean historical dramas.
