A lot of people I've had in my newsfeed I deleted because the crap they come out with is intolerable - from purely nasty, hostile verbal attacks on certain demographics to the annoying inane shit that seems to have boomed lately. Not as serious as your friend, but then I reckon there are a few active political issues in America right now.
The one person I really want to give a good yelling at, is my 14 year old cousin. She's a nightmare and shouldn't even have facebook.
