Child marriage with no minimum age is currently allowed in 5 US states, including California. We should probably be raising more of a fuss about that if we think a guy doing this 1400 years ago is a problem.

Between 2000 and 2018, some 300,000 minors were legally married in the United States.[16] The vast majority of child marriages (reliable sources vary between 78% and 95%) were between a minor girl and an adult man.[16][17][18] In many cases, minors in the U.S. may be married when they are under the age of sexual consent, which varies from 16 to 18 depending on the state.[19] In some states, minors cannot legally divorce or leave their spouse, and domestic violence shelters typically do not accept minors.[20][21]
