You are confusing religious tenet with men's interpretation. These are two very different things. And I say "men's" because it is men who are the greatest opponents of spiritual awakenings in any spiritual context.
Even the Norse had their Gods of love, Hinduism is certainly chock full of a variety of kinds of love. the last being a form of unconditional love. Judaism includes many expressions of unconditional love as the earnest way towards God. Buddhism also teaches unconditional love.
We can spend hours cherry picking parts of religious tomes that preach violence and say, "see? Look what they did to Canaan! Genocide!"
This ignores the messaging that runs through most religions that unconditional love is the final ideal. It occurs frequently in Judaism (read Isaiah for one example), Christianity, Buddhism, Hinduism, Zoroastrianism, and many First Nation religions.
I don't know much about Islam, but I suspect it resides in the Koran, as well.
But men will do whatever they can to promote their codes of violence. They spend a lot of time suppressing the teachings of love in their various liturgies. Deniers of faith also do this in order to justify their atheism.
I'd be interested in seeing where you say the message of love is contradicted by Jesus. I must have missed that part of the New Testament, or perhaps I've read some very poor translations.
