well you could tell them that road blockages are used by climate change activists in imperial core countries like Germany right now as a regular form of protest, and that the state responds by persecuting these activists as a criminal organization or even locking activists up pre-emptively for two weeks without trial because they may take part in such protests.

you could point them to :cool-zone: having happened less than three years ago, maybe then at least you could explain to them what it means when an event gets memory holed.
