Kim Kardashian -- You Can't Sue ME ... I'm a Hairy Armenian!

Kim Kardashian is seeking refuge in her hairy Armenian heritage -- asking a court to excuse her from a nasty beauty product lawsuit ... because she never lied about her fur-removal practices.

Kim just filed new docs in her ongoing legal battle with a beauty company called Radiant -- which sued her last November, claiming she's endorsing a competitor's hair removal product ... by making false claims.

According to Radiant's lawsuit, Kim falsely claimed TRIA -- a home laser hair-removal system -- works all over your body ... and yields permanent results. (Radiant says it does neither.)

Radiant is pissed, claiming Kim's misleading TRIA endorsement has put their hair-removal product -- called no!no! hair -- at an unfair disadvantage.

But Kim insists ... everything she ever said about TRIA -- including how she uses it all over her body -- reflected her honest opinions and experiences.

As Kim said under oath, "Being Armenian and hairy, I thought [TRIA] was the perfect product."

Kim is now asking to be dismissed from the lawsuit.
