What am I supposed to think when my Christian family hid a sexual assault and doesn’t talk about it?

I typed tbis story out in another subreddit and I may link it in replies or edit the post. Basically a cousin did something to his younger half sister when she was a kid. This cousin was 16 at the time and much bigger than her.

I wasn’t even told until maybe months or a year later when my uncle got divorced due to this incident. Certain members of my family didn’t know I know. Strange how they don’t wanna talk about it even though I grew up with them lecturing all the time when their kids got in trouble. The cousin who got touched has had behavior issues whenever she had come to visit. The family seems to want her to move past it. Mean while the cousin who committed the crime eventually got “saved” and he has been allowed to feel comfortable around us. I assume there are other members of the family that don’t know as well. Neither cousin has or can be around each other due to the judge’s ruling.

My issue with this is how my church going Christian family talks so much about lgbt being predatory. Meanwhile they hide this and don’t talk to us about this. I only know because one family member told me. These people constantly fear monger about lgbt when we live in the Bible Belt. I’ve hardly seen lgbt people here. Religious people and churches are in abundance though. Makes me wonder how many churches hide this stuff and continue condemning others
