I mean, I've talked to them in person? I've seen them countless times before this, and many of them have been organizing before Trump was president. Not only that, but I've seen the outcomes.

The local ICE rapid response networks in my community would not have nearly as many members had they not gotten tons of people at the last No Kings protest near me to sign up for their newsletters, the local progressive candidate would have been guaranteed to lose the election without the slim margin added from people at the protest becoming aware of their candidacy, and my reps probably would not have become more vigilant in their anti-ICE sentiment as a primary talking point over just a general wishy washy vibe of not being okay with it had they not seen so many of their constituents turn out.

My community has a progressive candidate in office who has plans to prevent ICE actions, police misconduct, and also make where I live more affordable, it has thousands more people on standby with whistles and plans to disrupt ICE activity if it happens near them, and it has my representatives voting no on funding ICE, instead of voting yes and saying "but we'll give them QR codes though."

If that's not a concrete positive outcome, I don't know what is.
