Are there any good arguments against gay marriage?
Not really. The vast majority of arguments against gay marriage are based on the Bible. The Bible has been used for centuries to justify some of most horrific crimes against humanity under the disguise of “God’s Law” or “morality”. People has always used the Bible to justify their on ignorance and hate, ref: slavery, witch burings, opposing women’s rights, the Crusades, the German extermination Jews, on and on. In fact, the Old Testament was even used as the basis to justify the Cruxifiction of Christ. If you actually read the Ten Commandments, the seven deadly sins, and the verses that are attributed to Christ Himself, homosexuality didn’t even rank a single mention.
