Facebook hoax/misinformation - stop and think for one second!!!

Anyone else sick if seeing (often well meaning /nice friends) on Facebook sharing nonsense fake articles/ memes which they think is true. They often are intended to spark fear or hate. Two examples I've recently seem are  include Muslims in xyz banning Xmas light displays, a sterilising drug put into women's drink at bars, fake photo of US ambassador's body... Ugh. Why can't people stop and think before posting fake crap.
