You've specifically picked left-wing examples, but let's not forget that the right is equally as guilty at manufacturing faux outrage as well. See the non-existent border crisis and migrant caravans as the most recent example. Other things I can think of run from Obamaphones to endless Benghazi investigations to "But her e-mails" This is amplified on the right not just by social media, but by self-styled provocateurs like Ann Coulter and Rush Limbaugh. The left doesn't really have any comparable outrage provokers. (Rachel Maddow maybe?)
