Was just giving this a bit of thought while cruising around on my lawn letting my tractor cut some grass for me... (just a very small bit; I was trying to relax...

)
I think the reason I don't view it in the same light is that the other enterprise you pointed out, Big Bulls, (Campbell's, was it?) doesn't purport to speak for the industry and to attempt to portray itself to the masses as representative of hunting. That's one of the biggest travesties of that fiasco called the WHA, and why it would allow anti-hunting sentiment to take an even stronger hold.
One portrays itself as hunting, when it's not. The other is merely a competition
revolving around hunting. Therein lies the difference.
