My home congregation was a very "protestant" Lutheran Church that identified with those who rebelled against the Roman Catholic Church. There were no crucifixes in our building, because that was considered "too catholic." Of course, that is a revisionist understanding of history.
Martin Luther did NOT break away from the Roman Catholic Church. He was not a protestant, but a reformer, and he certainly never threw away his crucifix out of a concern that he was too catholic.
We should not be so quick to throw out our crucifixes: we need to be reminded regularly of the cost of God's grace and not be so quick to seek the glory of God without understanding and being reminded of the gory of the cross.
