Pronoun Capitalization

[Neo-Scholastic]

I find it interesting that they use personal pronouns for their gods at all. It just seems ridiculous to talk about supreme creators and ultimate fundamental powers in terms of "he" and "him". I always use "it" myself; if nothing else I hope it rattles a few cages.

Ditto. I generally use "it" as well.

I've heard it claimed that the masculine usage is just for convenience and that god is sexless. If that's the case, why bother? "It" seems more suitable.

Because "it" is impersonal. A personal god requires a personal pronoun. Plus, even though YHVH does not have a specific gender, in Christianity our relationship with God is like that of a father and his children. So using the male pronoun is more of a doctrinal reference.
