That's genius there.
Not true. Aladdin and Auron both wield swords, and can do damage to Heartless/Nobodies when in your party. Leon is technically a swordsman, but is somehow capable of fighting Heartless without being outnumbered. Riku used a sword in Chain of Memories, and killed many a Heartless, not to mention Lexaeus, a major Nobody. And, if you play KH1 from Hollow Bastion, after Riku steals your Keyblade, you'll see the Wooden Sword does a very small amount of damage to the Heartless. Keyblades just happen to frighten the Heartless, which they could do if they were, say, a necklace or something similar.

Knowing your topic before you enter a debate is very important.
