I can’t stand the topics you mentioned either and I make a big effort to filter them out whenever possible! There’s a tool called https://siftrss.com/ which can be the middle man between you and your RSS feeds. It allows you to filter out any articles containing black listed keywords which is super handy.
My biggest frustration about modern RSS feeds is that the articles are often incomplete. Some clients are able to get the full feed anyway but it usually results in broken formatting.
