I almost caved

I came this close to commenting again at The Village Gate today... I had a subject and first sentence typed before I stopped myself.

What prompted my almost-off-the-wagon episode? This line by another commenter:

the Christian Right is pursuing a fear-based and extremist socio-political agenda that they're attempting to put a veneer of respectability on by cloaking it in religion.

Questions:

Who exactly constitutes "the Christian Right"?

What exactly is a fear-based agenda?

What exactly is an extremist agenda?

Whatever those things are, they must be very, very bad; how does cloaking them in religion make them respectable?

Do words mean anything anymore?
