To me it really doesn’t look like a call to genocide. In a democracy like Australia, religion is being defeated gradually by education, rational debate, and mockery when all else fails.

White people have tried to exterminate Aboriginal religions. Because these religions were seen as dangerous and primitive.

That was ethnic cleansing using religion as an excuse. That's not the same as doing away with religion. If your actual target is religion there's no reason to mistreat people.
