I'm confused, are you asking if you should be fighting patent trolls or patents? If trolls, then fighting them is better than not. Patents are tools, valid and legal, you don't fight tools, you use them, improve them, complain about them, etc.
Though seriously, I think the term landmine is loaded toward using patents exclusively as a troll. A wider analogy could be like a toll bridge, where the builder should be compensated by travelers. Some tolls could be usurious, but that wouldn't invalidate the whole principle.
