That's amusing, but not terrible relevant. Cross species romance is mostly pushing the idea that "two consenting adults" should be able to do what they want.

In actual practice, even with closely similar species, you'd probably tend to see human ships, Vulcan ships, Andorian ships, etc. At best.

While I agree that it was a proxy for social issues. I disagree about the assumptions for the rest. If certain earth like conditions were necessary for most intelligent life, it's not hard to imagine a similar comfort zone or temperature tolerance being shared. We simply don't have any examples to indicated if it would or would not be the case.

Single race ships might be good for social reasons, but completely unnecessary for biological ones.
