Missing the Point

I am still in Ethics. We are discussion Biblical justification in sexuality. Using literal interpretation, with no room for outside thinking, all things created by God are good. Therefore, sex is good because it was created by God. In an attempt to challenge my classmates to think outside the mother fucking cube, I tried something fun. I tried to compare cocaine use to sex. My point was not to try to justify the use of cocaine or other recreational drugs, however I do believe my attempt failed. Some kid just turned around and asked "Do you really think that marijuana and cocaine were around when God created the earth? Come on man." I chose not to answer him, not because I was defeated, but I saw that my point was lost. Literal translation without rational thought is deadly. I just found it humorous that I was actually asked that question. This crushes my hope for others.
