Platforms like twitter and facebook (and many "news" companies) brainwash their users, mostly by providing multiple different lies. Users pick whichever lie appeals to them the most, and they pretend they have found the truth.

To combat this, we need to emphasize the importance of thinking critically and verifying claims.

State the facts. Correct their misconceptions. Emphasize that billionaires are intentionally killing us all; lazy thinkers might reconsider if there is a possibility their life is at stake. I'm not saying threaten them, but we are all threatened by human greed.

The people you're talking to might not listen, but someone else might. Sometimes it just takes repetition to get through to someone, hearing the same clear message from multiple different sources.
