God's Blessing

From Religion versus religiosity by Paul Campos:

Choosing somebody like Warren is an insult not only to political progressives, but to religious believers (and especially politically progressive religious believers). It trivializes religious belief -- which I would bet even most of Warren's biggest fans will recognize as well, thus eliminating any supposed political advantage to be gained from this nauseating little exercise in pseudo-ecumenical posturing.

I’m OK with thinking that this is an insult to religious believers. I agree, and I think that it is a good thing to point out. But I do have a question. How do you trivialize something that is already trivial?
