Does Christianity = Opposition to Homosexuality?

Most people believe there is considerably more to being Christian than opposing homosexuality (itself a matter of debate). But such rhetoric is tempting and powerful for social conservatives, even if untrue. For one thing, it draws upon and misappropriates the notion that they are being persecuted. Beyond that, it implies that any Christian who affirms same-sex relationships is actually not a Christian at all. This is convenient, but it is also arrogant and highly problematic.
