Zack Ford at ThinkProgress has a list of ways RT contributors have spun Russia's war on LGBTs.
The video largely speaks for itself, but two quick points: 1) Setting the topic of Kirchick's remarks aside for one second, any network control room would have likely made the same decision to cut off a guest once it became clear he was hijacking the segment (others, however, might not have gone as far as to allegedly try to cancel his taxi ride that followed mid-trip to the airport). And, 2) RT hasn't technically ignored Russia's anti-gay law. It's more an issue of how they've chosen to cover it, as the AtlanticWire pointed out earlier today. A small sampling of RT headlines will give you an idea of the pro-Kremlin tilt on display: "Russian Jews outraged after Stephen Fry compared gay propaganda ban to Nazi Germany"; "Russia's 'gay propaganda' law causes outrage abroad but finds support at home"; and "Anti-gay law controversy ‘invented by media’ – Russia’s sports minister."
