Terrorism is simpoly what the government/establishment calls any politically motivated public action that includes crime or violence when anyone other than them does it.

4chan/anon was screwing with websites -> terrorism

Neo-nazis finding unsecured online printers at colleges and printing their propaganda -> terrorism

Shoot a public figure because you think they've done a tone of wrong -> terrorism.

Go on a bulldozer rampage against people who have wronged you -> terrorism

To be honest, it IS terrorism, by the very first definition.

First terrorists (named so) was revolutionaries (not bolsheviks, but other parties) in Russian Empire, who go to Government official's office and shot them in the face with Nagant revolver.

Look up Vera Zasulich, Dmitry Karakozov, Narodnaya Volya (organization), etc.

It is TRUE terrorism, not bombing Christmas parade or marathon.

I mean, it is. Just because you agree with it doesn't mean the label changes. And I don't necessarily hate what happened either, nor would I probably personally prosecute the guy. But lets not mince words, if you (try to) use violence against civilians for political/ideological/religious motives, that's pretty much the agree-upon definition of "terrorism".
