I think one can insulate themselves from the worst of the noise with some very selective follows/blocks/etc,

But anyway, re: your comment on the worst offenders, a related quote that came across my twitter this weekend-

"The surest way to work up a crusade in favor of some good cause is to promise people they will have a chance of maltreating someone. To be able to destroy with good conscience - this is the height of psychological luxury, the most delicious of moral treats" - Aldous Huxley
