I started on Lemmy.world, but found mander.xyz as a backup. Mander.xyz is smaller and has interesting science and nature content on Local without lots of negativity. It also federates with a lot of subs (including both beehaw and Lemmy.world) so I can still see everything in All.
Example of the above:
In the lead up to the Rohingya genocide in Myanmar, the government published a formal list of every recognized ethnic group in the country to specifically exclude the Rohingya. This allowed them to paint the group as “illegal immigrants from Bangladesh” (despite having been in the country for centuries), remove their citizenship and thus their rights to education and work.
