Only if you actively dislike the stories that you "don't like". I for instance often comment & discuss on news that I totally disagree with, and I keep seeing them regularly in my newsfeed. Also it depends very much on people that you follow. I follow many people with whom I don't share political views at all exactly because they share different stories with a different perspective than mine. That gives you a better understanding and also works very good to filter faux news, as one side will always approach it sceptically and debunk them quickly...
