I was recently talking to someone who had made the very poor decision to look at Twitter before going to bed. As a result, his blood pressure spiked, anger and vitriol flushed through his body and he couldn't get to sleep until 2 in the morning and had a restless sleep when he did.
I jokingly said, "You should have looked at some porn instead."
"I would have slept better," he answered.
It's not sex or nudity just like it's not having opinions or sharing them.
It's the gratuitous nature of it, it's the dehumanizing, it's the addictive tendencies, it's the abolition of risk and vulnerability, it's the cheapening of emotion... I'm not sure one is any better than the other.
