I have to say this tells us more about you than it says about Google. I never see such recommendations. The theories that I would look into if this were happening to me, which I reiterate it certainly is not, would be in the following order: perhaps you've installed an extension that is inserting content into your life; you are using anonymization techniques that mix your identity with that of other people who are interested in such content; you share a household with such people; you watch content that you do not realize is associated with right-wing content.
