Yes and acting like they are speaking the truth is truly a demonic tactic.
They are of their father, the Devil. The Devil sows seed, too.
John 8:44 King James Version (KJV)
44 Ye are of your father the devil, and the lusts of your father ye will do. He was a murderer from the beginning, and abode not in the truth, because there is no truth in him. When he speaketh a lie, he speaketh of his own: for he is a liar, and the father of it.
