I agree, I always feel like the "I always knew X was a bad person" discourse that always pops up in the wake of this stuff indicates that like. Somehow you had more knowledge than anyone else about this. It's basically just fueling your own ego as a result of a situation like this. You don't know these people, what makes people feel like a gut instinct suffices as sufficiently damning evidence? Like, it's fine to not like someone and abstain from engaging with them accordingly. That's okay. But going "I always knew that he was bad" does no good.
Obviously listen to Madison, trust victims and support them (do note that this doesn't mean not to listen to further developments and adjust your moral judgment accordingly, come what may) but that doesn't mean to indulge yourself and over-justify your ability to judge someone you've never had an interaction with based on vibes alone, that's a pretty unhealthy pattern to fall into in my opinion that has negative effects long term that don't benefit anybody.
