I'm gonna go ahead and step in here as a psychologist. Behavior only changes when there are consequences.
There are two variables in play here that the conversation is going back and forth on. The first is, do we know for sure he did it (and what is the context of him doing it)?
The second is, if he did it should there be consequences and if so, what should the consequences be?
Your comment is mushing it all together and spinning peoples comments.
The nice thing here is if we're patient, we will know number 1. Unless they used an encrypted software like what's app and they didn't save the messages, we will know all the information about if he did it and the rest of the conversation looked like. I think the problem that many people here are attending to is not taking the victim serious. Which is the sad history surrounding sex related laws in our country. These are also notoriously hard to prove because the evidence is temporary, and there are variables related to shame, embarassment, etc that come with sex crimes that prevent people from wanting to share.
So while we should take an innocent until proven guilty stance, I think we lose track of other things. If he were accused of murder, would you say "until he's proven guilty he should stay on the team"? If your answer is no, we're drawing an arbitrary line somewhere. At some point, we take allegations seriously and there are consequences while we sort things out. This is how the legal system regularly plays out. So if you think he should be the equivalent of suspended without pay while we investigate, I'm game. But this no consequences until found guilty thing isn't how the world works.
