Get radio equipment, learn how to use it. HAM radio is a capable, inexpensive place to start. They're already going after social media/ online communication. Twitter/facebook/reddit etc are perfectly fine deleting half their customer base over ideology. If you think your phone company /internet/ credit card won't freeze you out over wrongthink, you're wrong.

The ability to communicate with like-minded family, friends, and neighbors that doesn't require external infrastructure is paramount. We all have guns and ammo, I would say communication is even more important.

Imagine the antifags have a Mostly Peaceful Protest, fully backed by every branch of govt, the police are told to stand down, and simultaneously anyone who ever contributed to President Trump or was photographed in MAGA gear gets their communication shut off. A year ago I would've called myself crazy for suggesting this but it doesn't seem too far fetched these days. Don't get caught with your pants down.
