Well it is to be expected from places like Russia and India tbh. I am from the UK and such comments would be seen as shocking but we all know Russia hates gay people it makes sense that employees who grew up and continue to live in Russia are going to have very Russian views. Just because they work for a modern, progressive company such as Google (or Microsoft or Apple ...) isn't going to change their opinions on such things.
You would have got the same kind of responses in America if you asked about how blacks should be treated/integrated into the company back in the 1950s.
