This happened so often in the past. The N word bomb as proof of freedom of speech, the negation of the colonic interpretation, the conscious acceptance of retraumatization and the demand: hey, don't be so sensitive. It came from „nobody“ as well as known Devs, male and female. There’s also hardcore racist catholics beliefs ( don’t mix races it’s unworthy in the eye of god) who really  believe that they are humanities saviours, and have moral powers. Truly never! read such uneducated BS. 

 I'm sorry, if someone said that to you 😔, but "mixed marriages" in Catholicism refers to Catholics marrying non-Catholics. 

The Catholic Church has actually been one of the main forces in overturning antimiscegnation laws, worldwide, including in such famous cases as Loving because marital racism denies the universal priesthood and the sacramental nature of marriage.

Anyone claiming otherwise has not been properly catechized.
