what is ice?
you can't come to reasonable policy until you understand what this is: it's a human resources agency for capital. republicans take advantage of it's role in that context to fear-monger, whereas democrats (who are the historical party of the types of capital that ice works for) obfuscate and deflect, to make it hard to understand what they actually do - which you will learn is not what you expect, when you look into it and read up on it.
ice does not exist to protect the border and does not exist to protect the community. nor is it carrying out white supremacist policies under the direction of nazis (obama was deporter-in-chief, recall). it exists to do the dirty work of mostly agricultural capital in managing, controlling and regulating the flow and cost of labour.
and, you'll never fix it until you get it.
