Check out a great post by Internet Monk on what gays and lesbians hear when they listen to evangelicals. A sample of just one of his many good points:
One of the inevitable results of the information age is that anyone who wants to know the worst behavior of any group can gather that information easily. If one chooses not to be judicious and cautious with such information, it is possible to make every member of a group guilty by association . . . For example, saying that some gays somewhere have hundreds of sexual partners has little to do with the behavior of gays that I might know. As a statement of statistical truth, it cannot be applied in a determinative way to any individual. The average preacher is well aware of the extremes of sexual sin that probably occur among heterosexuals, but few would find it as easy to speak about internet porn addiction as promiscuity in the gay community.
What this says to the gay community is simple: evangelicals aren’t interested in the truth as much as they are interested in an emotional response. There is an agenda to how we process such facts and stories into communication.
But don't stop there. Be sure to read the whole post.
