First, Korean Martial Arts - General has description that says "Hwa Rang Do, Kuk Sool Won, Yudo, Kung Sul, Kumdo and more". I'm a Korean; I don't even know what Hwa Rang Do & Kuk Sool Won are. However, Yudo is Judo; Kumdo is Kendo. Korea & Japan pronounce the same Chinese characters in different pronunciations. You could fix the description to the following: "Kihapsul/Charyuk, Taekkyeon, Taekkyeon-Yetbeob/Sibak, Subak, Kooksundo, Gyeoksul, Bon Gook Gum and more"; those are the actual traditional Korean martial arts. Non-Japanese martial arts of Korea are not really well known. Second, Tang Soo Do has description that says "Tang Soo Do is a Korean martial art which teaches empty hand and foot fighting, fighting forms, self-defense, and weapons. Tang Soo Do also teaches people to live a healthy and harmonious life. This ancient martial art traces its lineage back 2,000 years to the Korean peninsula." Tang Soo is the Korean pronunciation of the Chinese characters Tode, Tote, Okinawan Te. It has nothing to do with Korea; it doesn't date back 2000 years. You could fix the description to the following: "Okinawan Tode in Korean pronunciation". I think such mistakes in category labels add to bias against Korea and my writings.
