"The attackers were people presumably brimming with the love of Christ" are digs at the righteousness of said Christians over the righteousness of others. Implied in the article, the righteousness of unbelievers is more righteous because their good deeds are done on the basis of being truly good-hearted and so on, rather than on the basis of (alleged) fear of a deity or looking good to others. 

If you can't see how that's self-righteous grandstanding in itself, or the irony in Ivo writing this, then you might be deliberately ignoring it. At any rate, the point of Jesus' quote is not to point fingers at others but to look at yourself and realise *we all do this*.  Heck, there's a sense in which I'm doing it right now. We all put our righteousness in front of others - the article is a case in point.

Thanks for saying at least I sound intelligent :) As to Jesus dying, I'm merely pointing out that Ivo misses the point of it, not that he has to believe it just because I do.
