What part of the Bible commands, or indeed even enables, Christians to hurl invective towards others for disagreeing with them? What part of the Bible enables any Christian to set him/herself up as the authority to whom others should turn for the authoritative meaning of the Biblical text?
Whether or not homosexual people may marry each other (and no Phinehastic quibbling, what is meant by that usage is same sex marriages) is immaterial to the duty of members to be civil to each other under the rules of the board, and the duty of Christians to show courtesy and respect towards others, even returning good for evil and a soft word for a bitter one.
What has been shown in this forum by and large is the inability of people who call themselves followers of Jesus Christ to obey even his simplest commandments as regards how they should bear witness to others. (Of course many such people believe in the Bible rather than in Jesus, and found their insults on selective quotation supposedly justifying them as "proclaiming righteousness," and I sincerely hope that He does not hold that idolatry against them.)
For the gay person, the "Good News" seemingly is that they are fated to live a life without love, and choose between being sneered at and castigated by the "good Christians" or living a lie about themselves. There is no promise of joy, acceptance, fellowiship, God's love, or anything but legalistic condemnation. If any of you wonder why your "witness" is so barren, consider what you are witnessing about. You have as much as told gay people that God's grace is not sufficient for them.
And for that you should be ashamed.
