God is not man. (Hosea 11:9) - does not talk specifically about Jesus so you can not specifically relate that verse to Jesus alone. No Trinitarian has ever claimed that God is a man, although one of the persons who is God did come in the flesh to bring us salvation.
Christ is a man. (John 8:40) Have you ever heard a Trinitarian deny that Christ is a man? Of course not so do not misrepresent the beliefs of Trinitarians. Trinitarians believe that Christ is 100% man and 100% God. It's your own fault if you want to ignore the verses that prove that Jesus is God in the flesh. You might want to read John Chapter 1 in it's entirety, not just the little snippets that INC tells you.
