How do I change this in my Facebook settings?

I check Facebook about twice a day. I’m a member of one American political party and one of my Facebook friends is the opposite. This particular person is a friend and my old classmate’s father. He’s not annoying except for when it comes to politics. He can’t make me change parties and I can’t make him change parties. On an almost daily basis he shares Facebook political pages, political links, political quotes, and political photos that appear in my Facebook RSS even though I don’t think I’ve ever typed to him about politics. He has now gone too far. I sometimes type about politics to other people, but never on an almost daily basis. I understand that there’s a way to go into my Facebook settings and change it so that a particular friend’s shares are blocked from going into my Facebook RSS. Maybe Facebook changed this so that it can’t be done anymore? Does anybody know how to do this? If nobody responds to this Wolf 3D Haven thread in about a week, then I’m just going to defriend him.

On news feed: upper right hand corner of post is down arrow. Click it, unsubscribe from... blahblah. Done deal. And unless he is specifically sharing them with you are tagging you in the photos, he's not sharing it with you specifically, he's sharing it with everybody.

Thanks. He was getting annoying.
