Damn good point. But (contra that) I believe that the Conservative position at the end relies on simple truth.
We may be paralysed in Alinksy's view, because we refuse to use poisoned weapons.
But at the same time, using deceit or dishonest techniques in the primary battle of ideas must tend to weaken one's ability to discourse truthfully - must weaken one's ability to be conservative.
Democrats are always hiding what they believe. They make you sign onto a "war against poverty" or onto the "pro-choice" movement. They use victims as human shields.
We do not. The very essence of Conservatism is to let our true ideas wrestle naked with the alien deceits of the Socialists. If we start using subterfuge to cloak our ideas then we deny our ideas their power.
"Conservatives believe they have better ideas. Leftists believe they are better people." And, they intend to make you a "better" person whether you want to be one or not."
True ideas aren't going to win the day.
