I have to say I am becoming heartily sick of the Left's “feelings, not facts” philosophy. We've seen it applied in so many situations, the most recent being the Michael Brown and Eric Garner incidents and the whole “rape epidemic” narrative being played out on college campuses. That they are willing to support such an immoral take on events shows me they have no regard for reality.
The campus rape epidemic caused by the so-called “rape culture” amply illustrates that they aren't really serious about the truth because it doesn't fit their narrative. If they hewed to the truth their narrative would disappear and they would have nothing to protest against. Therefore, it must be ignored, or worse, discredited through propaganda.
On more than one occasion I have lambasted those of a leftist bent during a debate by stating, loudly: “I don't care what you feel about (insert topic of debate here). I want to know what you think about it!” More often than not the response I receive is “What's the difference?” It has become that bad.
I think we must consider it some form of mental illness when they can't differentiate between reality and what they “feel” is reality. What's worse is that this form of dissociation is catching, something not usually associated with mental illness.
