It's not them as individuals that I worry about, it's their insidious takeover of institutions that can be serious opponents. I always get back to the virus analogy because it so accurately models the Left. They infect existing structures and institutions, things that were initially created for perfectly legitimate and worthy reasons. They then subtly (or sometimes not so subtly) manipulate the scope and mission of the institution, using them to advance the implementation of Leftist ideology throughout society. But most people, who have at most a casual interest in policy matters, continue to venerate those institutions based on their established legacy. I'm thinking here of things like education, the police, increasingly the military, and so on. Conservatives have traditionally been law and order type people, and part of our problem over the past several decades is that conservatives had this blind spot that left them unaware that both "law" and "order" were becoming increasingly the property of the Left.
