I suspect that Russia has delayed consideration of thls law that strips away the rights of LGBT parents is due to international pressure

Russia is hosting the Winter Olympics in 2014 and the World Cup in 2018, so I suspect that the Olympics and FIFA, as well as Western governments, have put massive pressure on the Kremlin to halt the enactment of future anti-gay laws, lest the moving of these international tournaments to other countries.

From BuzzFeed:

The move came to light after LGBT rights activists noticed the bill had been noted as “withdrawn” on the website of the State Duma, Russia’s parliament. A spokesperson for Alexei Zhuravlyov, the far right MP who tabled the bill, later confirmed the move, but said it would be resubmitted after some changes were made.

“It’s being recalled for revision — certain legal formulations will be clarified, and then after some points are removed, it will be brought to the State Duma again,” Sofia Cherepanova, Zhuravlyov’s spokesperson, told RIA-Novosti, a state-run news agency. “We hope to pass the bill.”
