Are you saying that Jews commonly practice fallacious reasoning:
A Republican is a Christian - therefore Republicans are anti-Judaism.
There is no logic in your fears. Jessie Jackson, Al Sharpton and Calypso Louis are all open anti-Semites and Democrats. I know of no openly anti-Semitic Republicans.
The KKK was almost exclusively democrats.
Are you saying that most Jews are ignorant, or just illogical?
Should Republicans just dumb down, lie, or exclude Christians from the party, or from seeking office?
My point was in my very first post. Go re-read it.
