If this logic makes sense, then it should apply elsewhere. For instance: "Klansmen and Skinheads and Timothy McVeigh reach out to people the rest of us could never reach, and preach the message of conservatism".
Bottom line: "We welcome anyone who wants to preach a message of conservatism, regardless of any other messages they also preach, or any of their actions."
KKK=Democrats
McVeigh=Atheist/Anarchist
Skinheads=Neo Nazis
None of the above carry or carried the message of conservatiism.
