Interesting topic, theorising (is that a word?) a scenario that might or might not happen. Nobody really knows what is gonna happen, guess that's the bottom line.
On this forum, even though there are more advanced incarnations here than in many other settings, spirits are on different levels. And in another setting, the regular joe, I THINK (theory), is more likely to panic, and be in a state of survival that will be of the dark polarity - me, me, me, at any cost.
Sometimes I end my participation in certain situations, and that's MY appropiate response to that situation. Other times I equally muster up what is thrown at me. I think of myself as friendly, but I'm not afraid of defending myself.
Now. I don't have a gun, and I don't plan to get one. Too lazy, too much hassle, but I'm sure I could find something to use for defensive measures if I felt the need.
I think if there is something to be learnt about dark domination such as wars etc, the dark doesn't give a sod about any fluffy words and.. love. I mean, really? If anything, I think it's percieved as weakness and an easy prey.
As for they who refuse to defend themselves in such a weird event, that's their experience and way of doing things, and I'm glad there are different roads to choose, to progress at our chosen tempo. I like it that way.
Worst case scenario, exit earth, enter astral and beyond. I (not the body) can live with that. :-) I don't know how I'll handle unknown scenarios, but as of now, I don't feel fear about this subject, and I think I'll be just fine whatever happens.
