And that's just TV news. I also stopped participating in unfiltered social media. No more Facebook except close friends or family. But if they start sharing garbage then they get muted. No exceptions. I'll go look at your feed if I care about what you're up to.
My "news" comes from highly-moderated, topic-focused groups. HN, for example. But I will gladly stop reading (and downvote) a comment halfway through if it's nonsense.
I'm not living in "blissful ignorance". I'm not putting my "head in the sand." I know what's going on in the world. I just choose not to be consumed by it. And my daily mood and outlook-on-life has improved dramatically because of that.
