I'm going to say this as gently as possible, but I think quickly labeling someone, "homophobe" or "racist" for saying something homophobic or racist similarly ends the conversation before it begins. The other person feels unjustly accused, rather than have his position questioned, and shown as homophobic due to its falseness, its unfairness, or its deroggatory nature, and instead, feel justified to continue their rant.
It's hard to enter into any conversation, and examine and discuss what was said, rather than label the other person, especially if it is insulting to us personally. It's human nature to attack those who attack you, but accomplishes little but make both sides justified to hate the other.
I think the same is said for mocking another's religion, no matter how impossible it may seem for you to believe. Religion, especially, is almost like the map that people understand of reality, and challenging that, or judging that, seems to cut a bit deeper.
RE: The rules, though, I keep going back the fear of legality.
I may say JC, and think it isn't blasphemous, while another may accuse me of blasphemy for it. If so, from a Buddhist perspective, I owe it to the person to tell them that allow it wasn't my intention, I seemed to have offended you, and so I'm sorry.
But then I am let to another dilemma, especially on CF.
I understand that this is first a Christian Forum, where people of other faiths are welcome.
My problem is that if a wolf chooses to put on sheep's clothing, they claim to have full authority of God's Word and Desires for us. They can claim that it is ok to hate, because God hates people who are worker of evil. Another forum had such Christians that would claim, for example, that Romans 12:9 Let your love be without hypocracy; cling to what is good, abhor what is evil. I am gay, I am evil, so God command them to hate me.
I would then pull up the whole passage. Paul says after that to love your enemies, return curse with blessing, do what is right in the eyes of all people.
I would then say that they have completely misused the bible, and are not following the words of Paul, nor Christ, but clearly the opposite. The are acting the antithesis of what a Christian should be.
Incensed, they would ask me what authority a non-Christian had telling Christian how to live. I told them that I wasn't telling them how to live, simply stating a fact, and point out what the passage spoke of. I exposed a lie, and was attacked for it.
And even as a Buddhist, that bothers me - people who act more like Pharisees, and claim to know God well, to follow Jesus, and yet, their fruit doesn't show that. For one, it gives Christians a really bad reputation, and its not in a good state now for a reason, but it also creates a really twisted idea of what God is. It shows God often as an ogre that would as soon crush you like a bug than save you, one whose compassion seems to end once you die, and he has to kick you into hell, one who is only about wrath, and not mercy, hope, kindness and love.
It is man making God in their own image, holding it up, and then trying to make others believe that God believes exactly what they do.
That's blasphemy, and I worry that if i call people on it, and Christ did to the Pharisees, that the legalese will side with the "christian" out of principal, or some specific wording loophole.
Were I a Christian, it is this brand of hateful, vengeful God that is presented to others that I would be far more concerned with when dealing with issues of blasphemy.
