As far as the defund ICE movement, it's just a small movement by a small set of people (namely AOC whom conservatives think is their modern red herring), lets not generalize and say all left leaning people want this when in reality they most likely don't, but you have to understand ICE has been abusing its power and it has also pushed to help create a massive private industry of private prisons housing "illegals" in which you could say should be defunded or more regulated since it's not properly handling people humanely nor are they helping the situation at hand.
