A lot of people try to get refugee status in the US, but the CBP puts them in open-air prisons in the desert. There are also are least 16 million undocumented immigrants living in the US. They don't all have to "sneak", they just overstay their visas.
The CBP was commissioned explicitly to enforce racial "hygiene" in the US. I don't understand how they weren't disbanded decades ago.
I'm cool with everything you said, except the gun control part. Felons are disproportionately POC because of our racist police and courts. POC will be disarmed disproportionately. Now, if we do some blanket amnesty, mass decarceration, and defund, disband, or disarm the police, then maybe gun control won't be enforced in a racist way. But in a country where literal white supremacist gangs run massive police forces, like the LASD, gun control will be weaponized against minorities. Also, gun control is classist and ableist.
He ran on getting kids out of cages and there is still a giant open-air prison for refugees on the border. He busted the railroad union. Those are two pretty big issues for the left. He's further right than Obama, and probably futher right than Nixon, if you compare their platforms. Fighting fascism by moving further right is a really bad way to fight fascism.
