@Zumbador I'm sure you'll get replies saying 'but I have to tell everyone, it's privilege not to read about it, blah blah blah'. I'm sure you know the sort.
I keep being undecided about whether to mute the climate change hashtag, though. On the one hand, like you say, I really can't handle the constant doom when it's something I already know a lot about. There's only so many times in one day I can handle being told 'we're all going to die'.
But on the other hand, I do quite like to see the hopeful posts. The ones like 'here's a new project/tech breakthrough/science discovery that can really make a difference!'. I wish there was a way to filter doom but not hope.
