Your “Following” feed only contains who you are following so the smooth brained right wingers shouldn’t show up there. If you see a smooth brained right wing tweet in the “For You” feed you can mark it as “Not Interested” and the algo will stop suggesting smooth brained right wing tweets.

Your snark isn't needed. I'm obviously not a user of the 'for you' timeline and still got those artificially promoted tweets from people I don't follow and were not retweeted by those that I do. It's why I stopped using twitter and I see no reason to change that.
