Depends on how it's done I think: breaking stuff vs sitting on it. And sitting on a highway is also quite visibly claiming the action, that is not clear in this case.
If this is XR, would be very dumb and against their message.
Yes and no. "rede" is a noun and has two syllables (ray-də) and means address (as in Gettysburg address). It's an archaic word, nowadays we would use "toespraak" (speech) or "lezing" (lecture). The word does share its origin with the modern English "to read", but no Dutch speaker would interpret "rede" to mean the same as a parent reading a child a bedtime story.
