Destroy Places of False Worship

Moses commanded the people that when they entered the land that they were to destroy all the places of worship where the Canaanites worshipped their false gods.  They were to tear down the Asherah poles and smash their idols.  How does that apply to us today?  Are we to go through our land destroying places of worship that don't worship the true God?
I was driving down Avenue Road in Toronto when I saw the following building.

This building was once the home of A. W. Tozer's Alliance congregation but it was purchased by a number company for the Hare Krishna.  Should we destroy that building?  Since we don't live in a theocracy we must allow false religions have their places of worship.  Our goal is not to destroy the building but to convert the people and thus make the buildings empty. 

I was saddened to see that this once glorious church now being used by a false religion.
