And why? Precisely because this nation was founded upon the Godly principles of fundamental morality as taught by Jesus Christ and as found in the traditional Judaeo-Christian faith...which teaches tolerance, doing good to others, treating others as you would be treated, and spreading those values through reasoned discussion and a winning of the heart and mind.
All of which is what the modern democratic party decries and opposes in principle.
Oh well...I have gone on enough I suppose.
