It's just the ever expanding march toward bubbles and safe spaces. It's funny we're here after decades of US prudishness on TV and media in general.
The internet seemed to open things up a bit, but now we have a new wave of outrage and moralism that seems to think they can tell everyone else what to think and feel, and what information they're allowed to see.
Kind of ironic that the internet is being used as a tool for censorship now, given what it used to be.
