spiking of trees - yes, a bad thing that the most radical of radicals do. However, these guys are as out there as the right-wingers you disavow. Most liberals do not support this.
the comfiscation of farmland - wha? Are you talking about the wetlands protection? Remember, both liberals and conservatives from farm states alike back farm protection. you throw this out as tho it's self-evident, but its not.
the distruction of whole industries in this nation, and the jobs that go with them. You mean like NAFTA, a conservative darling? Or the general march of progress? I disagree with the liberals and working-class conservatives on the need and purpose of protectionism - but to blame destruction of industries on "liberals" is wishful thinking.
Look at the Clean Air Act, which was supposed to have destroyed industry. Instead, it gave a kick in the behinds to smokestack industries, who ironically became more efficient as they closed crappy old factories and replaced them with new ones.
So of all the things you blame liberals on, the only one that's really a criticism of any liberals is tree spiking, and that's like blaming all of Christendom for David Duke.
