What does it mean to make your sukkah your established residence, and make your regularly established home into a temporary residence? Also, under what conditions would the rain drive one inside out of the sukkah? Plus, that rain in its capacity of Hashem rejecting our sukkot... Along with other natural events that are taken as omens (in the way that rain on Sukkot is a bad omen). What do we do with the scientific knowledge we have that explains some of those "omens," especially when we can predict when they're going to happen? Especially when the Gemara here pans homosexuality as the result of a bad omen - which largely offends our modern sensibilities.
