Thing is if there was any news destabilising to western democracy how likely are you to watch it on the BBC. If you want to get all the news including the stuff our government dosnt want you to hear then it cant do any harm watching RT to get a broader perspective surely.
The BBC reports plenty of news destabilising to western democracy, and has been full of it recently.
I would agree that accessing a variety of news sources to gain a broader perspective is good, but RT has proved time and again that it is a disinformation source, not a news source. Its sole aim is to undermine any news that is bad from a Russian perspective, by promoting counterarguments. Some of these have been utterly preposterous, but they only have to sow the seed of doubt for them to succeed.
A couple of months after the Salisbury attack I visited an Eastern European SP regular, who asked me anxiously about the"latest chemical incident" in London. I said I knew nothing about any such incident, and she replied that was because it was being suppressed in the UK press. Turned out RT had been posting a series of stories with the aim of making people believe that chemical incidents are not uncommon in the UK. Once you start to believe their lies, you are open to believe anything. As the saying goes, it is good to have an open mind, but not so open that your brain falls out.
