Truth is a human idea involving logic and language,
No, its not. Truth is what is , well, true. Truth is acutlaly independant of Humanity, and is not an idea at all. Truth is simply that which is a reality.

love is instincts from our mammalian ancestry,
Birds feel love. Its not Mammalian.
That said, Love is a Universal aspect int he Universe common to all living things.

When someone says something true about love, we're dealing with human ideas about human instincts. I hope this answers your question
You are , I'm afraid, mistaken.
Discuss arguments for existence of God and faith in general. Any aspect of any orientation toward religion/spirituality, as long as it is based upon a positive open to other people attitude.
