You did. There are valid comparisons in how the two are received, as opposing viewpoints are often nothing more than a plugging of the ears and yelling "LALALALALALALA" over the speaker. It has little to do with the theory/metric themselves, more how they're "refuted" (basically, without logic-based debate of the information). Of course, this does not apply to everyone. There are weaknesses that can be debated about both but that's generally not what happens. An example of this is USAChief, who has huge issues with WAR but instead of just saying "that's BS", he actually gets into the nitty-gritty of why he thinks it's BS. I may not agree with him but he's definitely putting thought into his reasoning why it's a bad metric.
