This is still a form of homophobia—to be forced into a relationship with someone to whom you’re not attracted just to meet some arbitrary social norm. Love among gay and lesbian people is not primarily about sex, but attachment and mutual understanding. Ancient society tolerating a few very powerful ancient leaders’ practice of “”loving”” concubines (who typically were not there by consent) does not equate to gay acceptance. Not even close.

This is not to mention that the traditional concept of marriage in China (and, to be fair, many other places worldwide) was more like a slave contract than a relationship. As you mentioned, marriages were arranged based on superstition and social position, rather than chosen based on love. And the woman was seen as an object being purchased, a domestic servant / baby incubator sold from one man (her father / family head) to another (her husband).

So yes, I 100% stand by my comments that Confucianism is sexist and homophobic.
