Nothing a good old kilogram of C4 to the Berlaymont won't fix.
That, I think you'll find, is the last thing anyone here would advocate, or accept you advocating.
The violence of citizens is great deterrent for oppressive governments. With most european nations totally disarmed, there is really nothing that prevents governments from passing extremely unpopular laws. Mob riots can be ignored, all non-violent movements can be neutralized in COINTELPRO like infiltrations and there is no threat to existing political system or public persons in that system.
The worst is that 1kg or even 10 tons of C4 will not change the course european union and western world are heading. I have no idea how to turn western world from capitalistic multiculturalist nanny states into sovereign, mononational socialist states, with minimal intervention capabilities in citizens life. C4 will not do much to change the rotten system, as Andreas Breiwik already demonstrated.
Deciding what the population can or cannot see on internet is just one small step to 1984.
