Yes God has told us all to destroy them. Posted some verses on that before. Here are some more.
Deuteronomy 12:1-3
1 These are the statutes and judgments, which ye shall observe to do in the land, which the Lord God of thy fathers giveth thee to possess it, all the days that ye live upon the earth.
[SUP]2 [/SUP]Ye shall utterly destroy all the places, wherein the nations which ye shall possess served their gods, upon the high mountains, and upon the hills, and under every green tree:
[SUP]3 [/SUP]And ye shall overthrow their altars, and break their pillars, and burn their groves with fire; and ye shall hew down the graven images of their gods, and destroy the names of them out of that place.
It is not tyranny, but rather the end of it.
