I don’t think it’s a logical fallacy. I do think the advisability of that sort of thinking is situational: if the half-measure solution is tenable, then it’s worth being open to compromise, but if the half-measure solution is almost as disastrous as losing completely you might as well be uncompromising.

Climate change denialists might claim that the Greens were in the first situation and therefore made a tactical mistake, while scientists might say the Greens were correct to reject half-measures. (You might think that sounds like I’m saying it’s a matter of opinion, but the crucial difference is that it’s actually a matter of fact and one “side” of the “debate” is simply factually incorrect.)
