She’s almost 70, spend all day watching q-anon style of videos (but in Spanish) and every day she’s anguished about something new, last week was asking us to start digging a nuclear shelter because Russia was dropped a nuclear bomb over Ukraine. Before that she was begging us to install reinforced doors because the indigenous population were about to invade the cities and kill everyone with poisonous arrows. I have access to her YouTube account and I’m trying to unsubscribe and report the videos, but the reccomended videos keep feeding her more crazy shit.
I listen to podcasts that talk about conspiratorial thinking and they tend to lean on compassion for the person who is lost. I don’t think that you can brow-beat someone into not believing this crap, but maybe you can reach across and persuade them over a lot of time. Here are two that might be useful (the first is on this topic specifically, the second is broader):

I wish you luck and all the best. This stuff is awful.
