Easier said than done, but yes, that's probably accurate 

 the state is a symbol

and both the catholic and orthodox allow some idolatry... it's notable that the protestant rejects both

the muslim, also, they have idolatry, they worship words... only the protestants come close to actually realising 

 Can you explain your definition of idolatry? 

 Confusing a symbol with the thing itself.

It can also be called a fetish, and Pavlov's bell is an example of making dogs confuse one stimulus with another.
