Yes because the idolatry of political leaders is bad.
Everybody idolatrizes the "founding fathers" and nobody finds it bad.
If you follow my posts here you would realize that I don't idolize the Founding Fathers and I certainly the 'cult' that surrounds them is very poisonous to American political discourse.
I didn't say you did. But since Founding Fathers are nearly-unanimously praised, that Washington and Jefferson are on mount Rushmore, then if we had to apply a fair treatment FDR isn't much "idolized". Of course, it also depends to how you define idolatry.
