There's a 3rd type of socialism that was more rarely spoken of in the 60's and 70's, because it didn't have the drawbacks of centralized soviet style communism and therefor was more difficult to demonize: Anarchism. This ideology was successfully implemented for a few years in parts of Spain during their civil war, and its success in creating a non-hierarchical decentralized and free society even attracted George Orwell to visit it, and join their cause to fight for what they were building.
It was eventually crushed by both fascists and communists, as both sides were terrified of that concept spreading. If we're able to implement it again someday, possibly in a spot where it would be much harder to crush militarily, then it would be a genie impossible to put back in the bottle, as it would be so self-evident in how superior of a way of life it provides to everyone, without the downsides of a centralized dictator.
You could warn your area if you see ICE around on this website.
Finding and getting involved in a local mutual aid group would be quite meaningful, as it would allow you to meet people who share your same concerns IRL, and be able to plan and organize for how to react in your area. It's very make a meaningful difference alone, finding a solid group is very important.
Attempting to unionize your workplace if it isn't already would be very helpful to further prepare for a General Strike (as they usually have strike funds to make a general strike financially bearable), which is pretty much our last non-violent option to prevent all of this from progressing. You can see how a general strike helped cripple Chile's government while civil unrest was occurring in this documentary.
I'd recommend contacting the IWW, who will gladly train you to become an organizer with proven techniques to unionize your workplace.
Lastly, I'd also recommend checking out the book Full Spectrum Resistance for a more complete guide on how to prepare and respond.
