Literally everything you listed was an opinion, not an independent reality. It seems like you won't be able to get past those to support BHA and the work they are doing. That's unfortunate. It seems like you are pretty upset about the opinions of some members, some association with mainstream companies like Patagonia, and support of National Monument Designations.
Perhaps you can take solace in that BHA partners with other companies that are more in line with your ideals like Kimber, Savage, Cooper, Weatherby, and others. Or maybe they also don't make the cut with their association with BHA?
You can come out and hunt a National Monument, and see what it is like, and you might find out why so many people appreciate the protection. The Missouri Breaks National Monument has broad support in Montana across the political spectrum with residents that live near and far. Let me know if you want to check it out, and maybe we can share a camp. Just like BHA's advocating, having these conversations face to face often make the most headway.
Cheers.
Edit to add:
If you are looking for someone a little closer to talk to about BHA, Virginia has the Capital Chapter of BHA:
Capital Chapter Board - Backcountry Hunters and Anglers
West Virginia doesn't have a chapter yet, but that board looks like a pretty grounded group based on those histories. Maybe they can expand on what they have going locally.
