Using Harper's Logic...

Cherniak has posted on Harper telling Dion that Dion's opinion on military matters is "irrelevant" because Dion has not served in the military.

By that logic, no one but teachers may comment on education, no one but police may comment on crime, no one but doctors may comment on healthcare, et cetera, indeed perhaps Harper will next suggest that only other Prime Ministers can critique him. What a stupid, stupid, cheap rhetorical trick.
