It can be. The bullied become the bully far too easily.
It’s like everybody was a nerd or a geek in high school, but all that means is that they weren’t in the cool clique and had to settle for being a theatre geek or a band geek. Very few were legit outcasts. That’s a bad place to be, because there’s no safe space to speak of.
I’m not being snarky. My opinion on Tumblr just differs from yours.
