Blurring the line between God and Jesus

What is it about frum people and their chronic inability to recognize Christian belief for what it is? I think the root of this phenomenon is that religious people become woefully uncritical when another person's faith is being discussed. We see it all the time at Cross-loving Currents, where a gay, hypocrite, Christian adulterer was lauded and praised by the very same people who routinely shove sticks into the eyes of left leaning Jews. And we saw it again today, from Gil Student:

[The publication of Mother Theresa's letters] created a scandal not, unfortunately, because of the circumstances by which they became public but because in them she confesses an almost complete lack of feeling of God's presence. She comes across as depressed, feeling abandoned by God and at times even questioning His existence.

However, as Gil knows, yet purposely obscures, Mother Theresa didn't reject God. Not exactly. She rejected Jesus. That's a sloppy mistake, especially for a guy like Gil.
