Luke 12:51-53 New American Standard Bible (NASB)
51 Do you suppose that I came to grant peace on earth? I tell you, no, but rather division; 52 for from now on five members in one household will be divided, three against two and two against three. 53 They will be divided, father against son and son against father, mother against daughter and daughter against mother, mother-in-law against daughter-in-law and daughter-in-law against mother-in-law.”

Since we're talking about at least self-identified Christians, I thought of John 17:20-23 (NASB):
[20] "I do not ask on behalf of these alone, but for those also who believe in Me through their word; [21] that they may all be one; even as You, Father, are in Me and I in You, that they also may be in Us, so that the world may believe that You sent Me. [22] The glory which You have given Me I have given to them, that they may be one, just as We are one; [23] I in them and You in Me, that they may be perfected in unity, so that the world may know that You sent Me, and loved them, even as You have loved Me."
Here I am not promoting any particular vision of what this unity may be in terms of doctrine (I am not saying that this forum should have an established church), but disunity and its fruits are probably a cause of unnecessary scandal.
I'll have more to say about this line of discussion in another post, which I hope to have soon. For now, I'll say that while I'd disagree with any wholescale removal of Religion Forum stuff from the site, the level of discourse could be more fitting of so great and important a subject.
James 3:9-10
[8] But no one can tame the tongue; it is a restless evil and full of deadly poison. [9] With it we bless our Lord and Father, and with it we curse men, who have been made in the likeness of God; [10] from the same mouth come both blessing and cursing. My brethren, these things ought not to be this way.
1 Peter 3:15-17
[15] but sanctify Christ as Lord in your hearts, always being ready to make a defense to everyone who asks you to give an account for the hope that is in you, yet with gentleness and reverence; [16] and keep a good conscience so that in the thing in which you are slandered, those who revile your good behavior in Christ will be put to shame. [17] For it is better, if God should will it so, that you suffer for doing what is right rather than for doing what is wrong.
