Google Posts Rainbow Olympic Logo -- Suck It Russia!

The guys at Google appear to have just flipped the bird at the Russians for their anti-gay laws ... posting a rainbow Olympics search bar to their homepage.

The art work popped up on the site minutes ago ... and the message sure seems loud and proud ... Google supports gay rights at Sochi.

As you know -- the Russians are enforcing a strict "no gays allowed" policy in their country ... which includes everyone traveling there for the Games this winter.
