So, are we obliged to genuflect to effort and sacrifice even if it's made in the service of a brutal and largely counterproductive cause now?
I really loath the "But if you don't agree with X, you spit on the orphans of everyone who ever died in the service of X!!!" school of argument. Dedication, perseverance, and sacrifice are really entirely orthogonal to the objective to which they are put. It's trivially apparent that you can find people toiling and sacrificing for all kinds of things, from the most loathsome of causes, to building life-size models out of toothpicks, to the noblest of ends. Working for a lousy cause doesn't change your degree of dedication; but neither does your degree of dedication redeem your cause.
