It's not that uncommon for people to block all that stuff out for personal reasons. Lemmy itself has some users that intentionally filter out all political stuff from their feed. I don't agree with it, but there's a lot of people like that.
It's not a good idea because at the end of the day even if you're not interested in politics, politics is definitely interested in you. Thse people are just burying their head in the sand and ignoring the real world.
Today for the first time in my life I've blocked keywords Trump and MAGA on Lemmy. Also took down my funny user handle. The world feels too real and too unsafe for funny monikers and constantly seeing the fuhrer's face again for half a decade. I'm not ready.
Politics on lemmy is a boring circlejerk anyway. Mods are even more ban happy than r/politics on Reddit. No political discussion of substance is possible.
