Ok? Then you don't have to expose yourself to it. I'm not arguing otherwise. There are many good ways to step outside one's filter bubble.

For what it's worth, though, my Twitter experience is pretty different. I follow a wide variety of people. Some of my feed is politics. A lot isn't. If you just have it show you a strict time-ranked feed and discourage it from suggesting stuff to you, you can tailor the experience quite a bit.
