I know there's a lot to read on the ol' internet these days, but this recommended reading comes in comic form with a really beautiful art style, courtesy of Mike Dawson and The Nib.
Why Did The Immigrants Come?
Long comic but short read. And it really effectively gets at the root of anti-immigrant attitudes and why they're fucked up.
"They did what they had to to survive."
And we punish them for trying to survive.
Let's not forget that white people came here from Europe looking for a better life in the first place, and stole this land from the indigenous population. We came uninvited and put up fences when we had no right to. We have no right to tell anybody who can and can't live here.
