What's wrong with blocking outlet that repeats propaganda of a state that was condemned at UN level?

... Do you think corporate outlets haven't repeated state propaganda?

Or that the US hasn't been condemned by the UN - many times?

Hmm.

I'm pretty sure US has never been condemned by the UN to the degree Russia is now. Even China and India formally acknowledged Russian aggression against Ukraine.

Also, if you are letting in some of one propaganda does it make you obligated to also let in some even worse propaganda?

The idea that you must do what someone wants you to do because if you don't you are somehow unjust or inconsistent is a known psychological manipulation technique.
