As I said, this board would demand the shell casings from our machine-gunning Prius before believing anything.

That's not relevant. How they would respond to actual evidence of riots does not change the fact that there isn't any evidence of continuous ongoing violent assaults on the ICE building out there. Saying that someone wouldn't believe you if you had proof of something doesn't suddenly mean that you do have proof of something. Whether other people on the board (not me) would refuse to believe actual evidence of people rioting for the last 100 consecutive days isn't relevant to whether that's actually a true description of what's been going on in Portland. It's not. As you've pretty much acknowledged.

<--- and here it is! The definitional narrowing.

What are you talking about? This entire thread has been about the fact that whatever's been happening during the last hundred days has not been a continuous and ongoing riot against the ICE building. No one's narrowing any definition. You posted a video of a woman complaining to protesters about how the noise is terrible - which is certainly a problem, but it's not the thing you were claiming upthread was happening.

It's not moving the goalposts. You said upthread that "[t]he locals should be locking up the people that are rioting for 100+ days in a row." You were asked for some evidence that people have actually been rioting for 100+ days in a row. Pointing out to you that the videos you posted of people not rioting are actually not evidence of people rioting isn't "definitional narrowing." There has not been "100+ days in a row" of rioting, or indeed any continuous and ongoing violent attacks on the ICE building that would warrant federal military intervention.
