Understanding slavery in Scripture for those who use it for a pro-homosexual agenda

Should we view homosexuality in Scripture the same way we view slavery in Scripture (as a reflection of ancient culture, not God's will for our times). This argument is going to become more common, and we as Christians need to be able to respond biblically that both America's slave trade and sexual tirades are violations of Scripture. This message also closes with the hope of the gospel to change hearts and gives a personal example in my family history of my great-great grandfather who was a southern preacher whose heart changed by the gospel and how that has changed my family. Be sure to listen to the end.
