TASS is an official outlet for the Russian Government, so I believe the offer is true and valid.

Furthermore, I have been following some families on youtube who have made the move, and are reporting favorably on it. And yes, the main reason is to offer their children to experience a life without those things that we all hate. For Cristian families it could be seen as a necessity, as their lives are busy enough already without fighting the disgusting system. There are also those who are facing persecution (Check out: Richard Medhurst - a second generation Christian peace-activist, arrested on terrorist charges in the UK (preposterous), today; or US' Tara Reade - such people may just want to get some peace and safety in Russia, already)

However, there are others who will want to remain and fix things at home, like Scott Ritter. And that's important too. Really.
