Does anyone else find it weird that God sanctions death yet condemns love?

Murder is the taking of innocent life, the Philistines were not innocent. Killing is different than murder. Philistines murdered and plundered and the Israelites were enacting justice. When Noah got off the boat God gave him a command to kill murders not murder murders. God's Love is not what sexuality between two men is. The definition of "Love" in the context of your question is different than what the Bibles definition of Love is.
