Well you described RT (or probably Russia/Kremlin) well.
They will come to Europe/US and say whatever they want and then when you say "hey Mr. RT/Russia/Kremlin/Putin, that's not true, please do not do this again", they will scream like bloody murder that you are restricting their freedom of speech.
I live in post-Soviet country, just before and during Ukraine conflict russian television (not RT) released "documentaries" which said that gulags have not happened, repressions have not happened, and after USSR collapsed, countries like mine were independent without any oppression.
That tv station got banned for a year if I remember correctly.
It's like Deutsche Welle would release documentaries in Poland/Israel/France/Check republic, that invasion/holocaust/concentration camps have not happened.
Your response that it's ok because "it's Russia" reminds me of a story that I heard. A man asks a doctor whether it's ok to pull the legs off a spider for amusement, and the doctor says it's not. The man asks why, since the spider isn't capable of feeling any pain. The doctor replies "I'm not concerned about what will happen to the spider. I'm concerned about what will happen to you."
