This is the place for discussion about firearms and related topics.
No fedposting. Be careful not to dox yourself. Talking about and owning guns obviously isn't illegal, but that doesn't mean some chud won't try to use information against you.
I highly recommend using a throwaway when asking for or giving advice that may include identifying information. Using Tor doesn't hurt.
This is a very tough question and one that I don't think has a good or right answer. I completely understand the hesitation to get training from a fash/fash adjacent group. Maybe figure out what it is exactly that you want from these training classes and find a way to set it up for yourself? I imagine it's just a series of drills that they will have you run. If you can run the drills yourself somewhere with friends, that's what I would do.
