Humphrey Carpenter has an interesting take on Carroll/Dodgson in his book "Secret Gardens" - he doesn't find anything particularly odd about his sexuality or his attitude to young girls, but he does find some deep weirdness in his attitudes to religion - which he seems to have detested despite having it as his day job. Everything in his published books (including the most famous ones) which seems to allude to God mixes up atheism and gnosticism to depict the Deity as a combination of stupid, evil and non-existent. He had much more cause to worry about what his contemporaries would have made of that.
