One would think so, especially after reading the Gospels.
But, as history tells us, religion and politics have a strong tendency to morph together into something that brings out the worst in both. With respect to Christianity, it went on for a very, very long time, starting a few hundred years after Jesus, and ending only recently in this country.
When you look at it one way, America was founded on principles of religious freedom. But you could look at it another way, and say that America was founded by people who couldn't compromise their religious ideals, so had to leave Europe in order not to be killed for fanaticism.
The Puritans weren't exactly fond of religious freedom for anybody but Puritans, and Rushdoony, et al., fit right into that tradition.
However, these folks don't believe they are "messing" with Jesus' teachings... they think they are clarifying it for us because we are too stupid to: 1) Read God's Word for ourselves 2) in the case of Catholics, remember the oral teachings and traditions delivered by the apostles 3)In general as Christians, do both... Hell NO, we need THEM to straighten this world out and make it safe for God... as if HE needed them to institute his plans. Seems to ME that HE has done pretty well with that whole "sunrise every morning" planetary-universe thing... without their or our help... heh heh...
