Q: Hello Dr. Craig,
With the recent Supreme court decision regarding same sex marriage I reread some of your Q/A response regarding homosexuality. In a question regarding the connection between interracial marriage and same sex marriage you said "Once we start down that route, anything goes: a man and two women, a man and a child, two men and a goat, etc. I see no reason at all to start down that road." with regards to same sex marriage. My question is does this statement constitute a slippery slope fallacy? My concern is that non believers would easily dismiss it.
