As it stands, the need for violence is being encouraged in suspicious ways as possible grooming operations. Different sites encourage extreme content/propaganda against the "other" and this in itself is a political ploy by some nefarious leadership to divide and conquer the populace while bolstering themselves once the dust settles, and after the astro-turfed purge. The best thing to do with this is to not play into it since senseless violence is a problem to begin with. Now to use violence against a stronger opponent in order to defend yourself or a loved one is different but you can't go around killing innocents under a political motivation echoed through some propaganda because its part of your final fantasy of things.

So the basic guidelines are still the same, be original while questioning things and stick to your ideals. There isn't really a proper instructions manual on how to fight all the time. Everyone has to figure it out for themselves and their own tactics while figuring out their own motivations. If however, anyone is trying to motivate you into attacking, then; that is possibly the enemy that seeks to gain from your failure and you should question it beforehand.
