Before I continue, let me say that I agree that cutting old-growth (or any trees that aren't on tree farms) is a bad thing that we should stop doing.

However, you are making a false equivalency here. Engaging in an act whose sole purpose is to maim and kill other people is nowhere near the same as engaging in an economic act that produces long-term harm. 

Trying to kill people is something that should be a felony and get the perpetrators thrown into prison. Harmful economic acts need to be stopped, we agree, but none of the legitimate ways to accomplish this involve violence.

I hope this clears up my stance. I am not advocating or supporting cutting old-growth trees. I am denouncing attempted murder.
