Have a look at Dennis Byrne’s takedown of Martin Marty, who unfortunately questions Byrne’s knowledge of and dedication to Catholic principles.

Nicely done, especially when he gets to the part about questioning one’s Christianity because he likes not a government program.

It is not a necessary part of church teachings that commitment to the common good requires the support of this or that government program that addresses societal needs. Christ’s directives to do good can be applied through other means than government programs.
. . . .
At base, Martin’s perspective is a typical slander made against people who feel as I do. Because we do not support a particular government program, we are accused of having no compassion or caring for the downtrodden or even the “undeserving.”

Yes, Marty, there are Christian (even Catholic) conservatives.
