You could create an account that blocks off communities for news and technology, and any other communities that have a high likelihood of reporting on current events. Just switch to the account on days where you just don’t want to read such news, for any respectable reason you may have (it’s understandable, it can be draining).

This should be a no-brainer, but Lemmy doesn’t really filter stuff out by default, unless the admins decide so. So as long as you’ve created an account on a fairly managed instance, and given that the current news cycle, especially in the Western & English-speaking world, you won’t be able to escape Trump and Musk, especially when they’re dominating headlines due to how they are literally affecting the lives of millions, if not billions, of people.
