1) Fear of or contempt for lesbians and gay men.
2) Behavior based on such a feeling.
From Jeff Sharlet of the Revealer:
"Homophobia is a cross-party persuasion, but last night it figured most often in the votes of Republicans. A topic discussed more and more frequently as the pundits came to realize that their predictions had been wildly wrong was 'values' -- that is, in this election like no other, gay marriage. Let’s make that simpler, get to the root of the matter: gay sex."
When did making a moral decision about sexual activity or legally enforceable contracts become an issue of fear or contempt? Why is my evaluation of the biblical texts on homosexuality a fear-based decision, when my evaulation of the biblical texts on adultery a morality-based decision? Why have we let "homophobia" become so broadly defined as to include rational moral judgments?
