I just read the line "I am not against multiethnic families in principle" from a nominally leftist account before they went on to expound on how only a few people are qualified to form one and you know what, fuck Americans and all their works. Full offence.
There is absolutely no qualifying statement you can make to your idea that multiethnic families are inherently abusive that makes it less insane, and in no world will it be an interesting point, because people falling in love and having babies is an intrinsic good.
