Fundamentalist Christians pick and choose biblical passages to support their own point of view. As this woman sat their declaring homosexuality a sin,I wonder if she realized that she held the very same book that was used to justify the enslavement of African American people? Pick a bigotry at random and I am sure you can find someway to justify it in the Bible.
As much as religion did enter this discussion, the issue is not Jesus or Christianity but heterosexism. Religion is only the tool which is employed to justify oppression.
