OK, we are definitely together on these points.

Deducing God's actions or motivations from simple logic can very easily be self-deception.

On the other hand, there is a point where to ignore logic entirely would be to make oneself insensitive to reality and in particular to suffering. The deduction "God surely would not have formulated a "God's plan" that involved everyone being heterosexual even though large numbers of people by nature had no significant experience of the necessary impulses" is a bit like deducing "God surely wouldn't actually have created one entire race (sons of Ham, i.e., Africans) to be the slaves of the other races." Sometimes these logical decisions just have to be made between "God appears incredibly arbitrarily cruel but this is actually some sort of love we just happen not to understand" and "God has a love that really must be something like the love we can understand and one that doesn't involve making lives of ongoing torment."

Don't be too careful. Just imagine you were back in Abe Lincoln's time thinking about abolition: would you have been sitting there saying "don't forget to say 'maybe'" about re-interpreting the "sons of Ham" passage?
