What does telling them have to do with reality?
I believe Jesus chose to do the will of the father that resulted in Him taking on the sin of the world.
We are not to entangle ourselves with the unclean things of this world but this doesn't mean we are not still in this world. To separate completely we would need to be dead. God's wisdom can help any situation no matter the topic.
And while it's nice when people agree, I don't base my faith on how many people agree with me.
