Earlier quoted context omitted.
If you don't like what your friends post to Facebook then you should reconsider if you want to be friends with them, or if you should begin using the tools FB already provides to control the content in your feed.
Many people use facebook as just another way to communicate with friends, either through messages, wall posts, or event invites. I don't really care if they post uninteresting stuff to their own wall. Actually, it'd be rather sad if I reevaluated my friendships just based on that.
This is unfair, you responded to someone who was saying "If you want a higher quality stream, then curate more aggressively using the tools available to you"
And I feel like you ignored the meat of his post to make a cheap shot on the idea of "losing friends over memes". That wasn't his point, and I think you knew that. The tools he mentions allow you to control what appears in your feed without unfriending.
