> There's little I can do
I use https://hackersmacker.org to mark them with a red dot so I can skip those comments. It's like slashdot's friend/foe system (including social aspect). There are also plugins that allow blocking and filtering users.
I'm, personally, here to interact with people interested in tech. I feel no shame in curating my experience to fit that. If I wanted to be saturated in politics, I would make a Reddit account.
