That doesn't justify lying
Right. Because some veterans are unhappy about the fact that John Kerry opposed the war in Vietnam upon his return from heroic service to his country they apparently have a "right" to lie about his service record. What a load of crap. The American right is a bunch of lying assholes.
By the way, most Americans opposed the war in Vietnam. That's why Nixon extricated us from the conflict after 50,000 Americans lost their lives for no good reason.
