I like Voddie Baucham (pronounced Vo-dey Bau-kum). He has a great way with words and is a fantastic preacher. He's also black, and he does a magnificent job of approaching racial issues with a biblical and theological perspective.
In this really good article he takes on the notion that "gay is the new black," and the subsequent assertion that homosexuality and the issues that surround it (like gay marriage) are civil rights issues, which Baucham persuasively argues against. This is definitely worth reading.
Perhaps the best part of the article is the conclusion that Baucham comes to. Although there are many logical arguments against homosexuality in general and gay marriage in specific, and although there are mountains of statistical and social data that back up the Christian position, these are not what we must appeal to when addressing these issues. Rather, as Voddie says, "It is very important for those of us who oppose the idea of same-sex "marriage" to do so not because we wish to preserve our version fo the American Dream, but because we view marriage as a living, breathing picture of the relationship between Christ and his church, and because we know that God has designed the family in a particular way. While the design of the family promotes human thriving, the testimony points people to their only hope in this life and the next. As a result, silence on this issue is not an option."
