It's a matter of opinion

I do think that either there is a hell or there isn't. The term "matter of opinion" is inherently ambiguous, since the phrase is used for things that are neither true nor false (McDonald's burgers are better than Burger King's) and about which evidence is irrelevant, and about things where it is either true or false, where evidence is relevant, and but where there is no overwhelming evidence either way. The question of whether or not there is a God, or a hell, is, in my view, a matter of opinion in the latter sense.
