Simone Biles is publicly attacking her former Team USA gymnastics teammate Gabby Douglas -- and it's all over comments Gabby made insinuating some women invite sexual abuse by the way they dress.
It all started with Aly Raisman ... their 2016 U.S. Olympic teammate who recently went public with allegations she was sexually assaulted by ex-Team USA doctor Larry Nassar.
Raisman -- who famously posed nude for the ESPN Body Issue -- received hate from people who shot down her story because of the provocative pics.
