I agree. I feel like people amplify their emotional reasoning to the extreme with social networks enough to jump into whatever moralistic "shoulds" or anything that can get them behind the "right", sort of like putting your morals on the line in a popularity contest, a hell of a emotional rollercoaster.
People seldom take perspective and context in account. Especially if they all go into the angry mob mentality as you mention which I'm pretty sure we have seen plenty of times.
