I get the trad-only thing but...all of my hunting buddies shoot compound bows except me. Frankly it is a non-issue as we go places to hunt and hunt hard. Weapon choice is just that, each person's choice.
So I think trade only is interesting, but I would prioritize things in this order:
1.) Great place to hunt various color phase black bears that accommodates bowhunters
2.) A place I can go with my friends
3.) Go back to item 1
4.) Ok accommodations - dry place to sleep, ok food.
5.) Go back to item 1 :-)
6.) Bow only
7.) trade only (this is likely further down the list than 7 for me)
I have bear hunted in a shared camp with all weapons and I didn't care. The outfitter knew bears and had bowhunting stands and gun stands. The folks we met in camp were nice and I got to go hunting with my compound bow carry best friend.
Also, the hunting is what matters to me most and like most bowhunting, I do this alone so I don't care what you are doing (carrying), I care what I am doing.
So since you are asking, I would not limit the camp.
I would also guess that trad bow shooters are just like any cross section of people in this world, most are nice, some or ok, and a few will be arses top to bottom. :-)
