You may not be seeing what I see. I see conservatives who understand that people are flawed but also notice the characteristics of a liberal attack. You see we notice that liberals (especially the MSM) avoid attacking the ideas and concepts that they cannot compete with and attack the messenger. They require that the messenger has to be pure and right about all things in order for their message to be without flaws. It is a tactic that most of us have grown to lose our patience over.
Oh and welcome to FR and when you generalize about conservatives you are likely wrong so this may not be the best place for you.
Leftists fault conservatives when we fall short of our high ideals.
Leftists with sortcomings are excused from criticism because they have no aspirations to higher ideals.
