Premarital sex and homosexuality have also been around for thousands of years, but I think it's safe to say what is generally accepted by the mainstream ("of our default educated east coast beliefs") would shock & awe the mainstream of the 1830s.
We can sort of account for pre-marital sex, since most fathers, irregardless of the century, don't like the idea of their daughters screwing around too much, but what they like even less is them getting pregnant prematurely. Society has invented solution for that latter.
