"There is a God" is also an opinion, no more or less so than "Ice cream melts too fast." We, as audience, have the ability to discern statements made that are opinion from statements made that are fact. If there's any burden, it's on us to make that distinction and treat the statement accordingly.
I'll accept that, then, even if it is a little subjective.
