I find it problematic that there have been oodles of very classical kinds of 'terrorism' and 'extremism' on Social Media since the start.

ISIS has been recruiting with absolutely brutal kind of stuff on Twitter, etc..

But now we have this nutbar thing in New Zealand and it's a 'global action'?

Aside from the complications mentioned in some other comments ...

... the Jacinda / Trudeau / Macron triumvirate I think were looking in the wrong places.

So it's probably good that we're taking action, and just beyond repulsive that that some massacre was broadcast live on Facebook, but I hope we accomplish do this without too many existential issues.
