Why not? It's not as is world-wide condemnation has forced politicians in countries where homosexuality is illegal to repeal those laws. In fact, the opposite is the case, where these countries are making the laws even more anti-gay. Russia is demonstrating a dismissive mentality towards the rest of the world. It literally pulls the finger on any criticism of its draconian laws. If Russia were to move to re-criminalize homosexuality, there would be condemnation, but that condemnation won't matter at all to Russia. It'll just go forward as it seems intent on doing making lives for gays miserable.
