Yea, unfortunately you really need to visit New Hampshire to see what it’s like. The forums and public outlets really suck. On Matrix it’s mostly trolls at the moment. I’d probably check out the New Hampshire room on Matrix if you check it out. Pretty quiet though. The forums don’t have much going on besides a few people saying hi. Maybe this will change as they get more active again. This is they are getting busier, but it’s new people, not real chatter among those in New Hampshire. Mastodon is OK, but it’s also still fairly new. The best outlets are actually currently those that are restricted to those who have moved on Telegram.
I suppose there are some that aren’t like the Freedom Decrypted channel on Telegram (linked from the web site below). That might be a good place if you are technical to see what it’s like in NH.
I’d actually say the best way to get a feel of what it’s like to be among liberty minded people in New Hampshire is to start listening to Free Talk Like. It’s mostly one-way, but it’s definitely a good mostly friendly group. If you are a technical person check out Freedom Decrypted. It’s a similar ish podcast in a similar format to Free Talk Live. There are also other shows on the LRN (liberty radio network) although I think there are people from outside New Hampshire too so it’s not quite going to give you the same feel. People who migrate are certainly more unique and I’d say interesting to say the least.
