It does not appear, as the OP subject suggests, that "Obama Pushing Shooters Off Public Land." The 'subject' is a blatant lie.
The article referenced in the OP directly, clearly, and most emphatically refutes your assertion:
"Gun owners who have historically been able to use public lands for target practice would be barred from potentially millions of acres under new rules drafted by the Interior Department, the first major move by the Obama administration to impose limits on firearms." This is the key paragraph foes say could lead to shooters being kicked off public lands: "When the authorized officer determines that a site or area on BLM-managed lands used on a regular basis for recreational shooting is creating public disturbance, or is creating risk to other persons on public lands; is contributing to the defacement, removal or destruction of natural features, native plants, cultural resources, historic structures or government and/or private property; is facilitating or creating a condition of littering, refuse accumulation and abandoned personal property is violating existing use restrictions, closure and restriction orders, or supplementary rules notices, and reasonable attempts to reduce or eliminate the violations by the BLM have been unsuccessful, the authorized officer will close the affected area to recreational shooting."
Since these measures are undeniably supported by Obama, this most certainly appears that Obama is pushing shooters off public land, and is not, as you falsely allegate, a "blatant lie." If anything, it's the blatant truth, which relegates your comments into the bin of untruthfulness.
Your support of Obama is well-known here. When you have to resort to untruthful tactics in support of him, what kind of impression do you think that leaves any of us with respect to the integrity of Obama and anyone supporting him in this manner? Quite frankly, my impression of the integrity of this approach is rock bottom. It's not unrecoverable, but any attempt to justify the deceit only serves to further bury what little integrity may be left.
There are two ways to approach life:
1. Wade in with an ideal and use any and all means necessary to garner support for your ideal.
2. Gather as many facts as humanly possible and all the facts themselves to dictate the stance one should take and defend.
The former leads to lunacy. The latter leads to reality.
