There are various ways those attacks can happen, ranging from Greta Thunberg's non-confrontational style
I've never seen her speech but I know the jest of what she is saying. But you wouldn't believe how many Greta Thunberg haters their are in the US. I guess it's because she shed a negative light on Trump. But for a while FB was just flooded with nasty faced images and hateful little remarks. It was amazing how much energy was spent on smearing that young little girl. It was actually quite shameful. It astounded me how much affect she had on people, where as all the science and scientist are easily dismissed.

I'll have to admit I don't know what this means, "War without firepower". Thought maybe it was a movement of some type in the UK but when I Googled it I got nothing. Must be a term used by people above my pay grade. lol
