Yeah - goll-dang Facebook.
IMO, it should be reserved for pictures of your family and funny stuff.
The rest is just an obnoxious soap box for us to argue from and never really solve anything. Cripes. It really should be limited to kittens' shenanigans, family photos and Star Wars memes.
Good for you - unfriend, unfollow and block anyone that mucks up your feed - even family!
