politics can actually be followed or unfollowed like any other stream.
If you unfollow, then you won't have your personalized Imgflip front page cluttered with the RWNJ nonsense that is omnipresent on the politics front page. Which is what I recommend.
However, because politics is a main stream of Imgflip, it will always appear in your drop-down window of streams followed, even if you don't follow it.
And because it's a main stream, you also retain the ability to submit to "politics" at all times whether or not you follow it.
