I don’t think that you should simply state that “leftists are more inclined to lie and slime,” because it’s deeper than that. It is more appropriate to state that “leftists are more inclined toward moral relativism” then observe that:
If the ends justify the means, then there will be occasions where lying and sliming are justified by important-enough policy goals.
I think that an attachment to moral absolutes, be they Biblical, Koranic, Randian, or whatever, will preclude short-term advantageous behaviors resulting a greater perceived, if not real, degree of integrity. Thus, I think one should ask first, is s/he a moral relativist or not? And then decide whether to count the silverware.
It’s interesting that even when you look this story from a perspective of moral relativism, the lies and sliming of the left have been dis-advantageous because they were found out. Thus, to pull off moral relativism, you have to be infinitely smart anticipating all of the consequences of your actions. Good luck with that. If you aren’t, you just end up like Wile E. Coyote, super genius.
