I don't follow this stance when looking at the image.
I believe the image is saying the democrats supported ICE until 2017 through 2020, when trump was in office. Come 2021 and the democrats are back in office, they continue to fund it. During the second trump administration, they are back to denouncing ICE.
I think funding is used here in the context of what the democrats were calling for during the first trump admin. For example in 2018: https://thehill.com/homenews/senate/394978-warren-its-time-to-replace-ice/
Focusing on a wider range of candidates: https://www.ctvnews.ca/world/article/some-democrats-with-eye-on-2020-abolish-ice/
However, by 2020 the views had shifted: https://www.washingtonpost.com/graphics/politics/policy-2020/immigration/abolish-ice/
And after the election abolishing ICE was no longer a priority.
Do you think what ICE is doing now is a fundamental shift from caused the initial outrage during the last admin, rather than just a jump in magnitude?
Even if I imagine myself as someone who thinks reform is possible, I can't understand how the view isn't that by maintaining the status quo the dems have exercised terrible negligence. If the behavior of the first admin was so abhorrent, wouldn't it be critical to ensure a future government couldn't as easily do the same or worse?
