1st of all, if you're into politics and can't resign from it, replace the sites you know, with those that deliver news in as neutral tone as possible, with as little toxic inclusions as possible. AXIOS is one.

2ndly, use Feed Reader like INOREADER and consider sbscribing to one of its non-free plans to get the tools that filter out news by keywords, phrases or similar variables.

3rdly, prioritize what you actually need, instead of stuff that might be "somewhat" relevant to your interests. For example, if you have some good, reliable source of news/content on video games, then skip the rest - they tend to cover same games in similar time span, so you won't miss much when you reduce your feed from 10 to a single site.
