How narcissism became the modern plague

HBO 's " The Mountainhead " has a "Dr. Strangelove " level of absurdity in its plotting, but feels almost understated in its satire of the ridiculousness of our era.

The movie works only because it's ruthless in its portrayal of the ego delusion that fuels Silicon Valley's C-suites.

Everywhere you look online, people are talking about narcissism.

Frida Ghitis: Liberals are right to be worried about this phenomenon because narcissists aren't just annoying, they're dangerous.

She says the fascination with narcissists isn't just about surviving an era where we're terrorized by them; it is also about our egos.

Ghitis says the fear of being narcissistic understandably haunts so many of us in an era of social media.

Social media was meant to connect people to each other, but it's encouraging people to turn inward in ways that harm them and others. It's probably why voting for Trump got easier for some folks after they spent way too much time online. So yeah, it's good to hate on narcissism. Maybe it will convince more of us to try a little harder to be less self-obsessed..
