Well, I disagree with your opinion that cattle grazing doesn't destroy anything.
I don't believe government knows best. Sometimes they do and sometimes they don't. Our democracy depends on an educated public.
Overgrazing Can Hurt Environment

An educational tool about cattle grazing
It doesn't harm anything, any rancher with an ounce of common sense knows about over grazing and that is why cattle are moved from place to place. Fact is there is no better conservationist than ranchers, farmers, fishermen and hunters. Conservation groups have worked with ranchers using their cattle to restore native plant species by grazing invasive grasses. The point is, ranchers are better suited to managed grazing land than Washington bureaucrats are.
OK, so due to stubbornness, naiveity, or dishonesty you are ignoring the four links I gave that showed why grazing lands needed to be managed by someone other than the individual owners. You want to use an old stereotype of the rancher, farmer, hunter, fisherman that no longer exist and ignore the damage these groups have done over the years as documented in these studies. You want to ignore facts as presented in these studies, three of them by universities with well known agriculture studies and departments, including one very pro grazing study from Texas A&M.
Sounds like your agenda is something other than protecting grazing land. Sounds like you fit the profile of a person jumping on someone elses issue and twisting it to fit your own political agenda without regard to how it hurts the other guys agenda. You pretend like you support the other guys agenda, but in reality you are willing to burn it down for a cause you think is more important than the other guys. The folks who don't want to hear motorized vehicles when they hike in the desert are not important because the ATV riders want to ride anywhere and everywhere they desire. The folks who want to appreciate the archaeology of an area don't count because the motorized vehicle crowd demands to be able to ride everywhere and anywhere they want. No matter that there are 2,000 miles of trail appropriated to ATV's in a county, you will refuse special use to even 20 miles for others. And if you don't get your way, break the law, call in the militia.
Go ahead a run with that strategy. Lets see how it works out.
