This is leads me to interpret your response less as a genuine concern for specificity that lead to constructive criticism, and more as "I don't like this subject—therefore I will express disagreement with something you did to indicate that."

The subject of LW is refining the art of human rationality. Telling people to be more precise when discussing political issues is on that subject.

This isn't reddit and I wouldn't like LW to become like reddit. To do that it's important to defend a certain level of posting quality and speak up when that's violated.

We have recent discussions about whether to ban political posts. I'm not in favor of banning but I'm in speaking up to have those discussions on a higher quality level. If you would ask the same question on http://skeptics.stackexchange.com it would be closed as being too vague and to have questions like this on LW without being criticized.
