I can appreciate the don't ->-bleeped-<- with me feeling, but in my opinion, yes, the post was a little aggressive. How your friends react, will of course, depend on your friends. Recently I unfriended a baker's dozen of old friends from Houston who I realized gave me the "we will always love you" followed by the "we need some time to adjust to it" and silent treatment routine. However, I gave them a chance first to show that they would roll with it. Once they didn't, I cut them off. This way I guess is more of a "get with the program or there is the door" approach.
