I think it's perfectly acceptable to speak out against inappropriate behaviour and even more so if the person to whom it was directed has said they didn't like it. And he might not have been "copping a feel" at the water cooler, but he was grabbing his crotch and gesturing when celebrating in the stands, which whilst not necessarily connected, adds to the picture of him.
"Oh he got carried away", "oh he was just celebrating" etc. excuses and condones the behaviour.
Poch the Crotch used to grab his, in fact he did it more than once, several times infact, I wouldn't paint a picture of him because of it, I would probably suspect its something abit more cultural than sexual even if its not a good look.
Im not condoning the behaviour, I am saying that people being judge juror and executioners on situations they are not in, not party to the full picture and also in many cases lacking context is not something I am all to comfortable with. The fact after the heat of the moment she has come out and defended the guy suggests the situation was part of the bigger picture. Each incident has varying levels of gravity to them, and therefore the right to be judged on its own merit, not under the weight of history
For me its a situation for the victim to decide how she feels and act accordingly, not me to tell her what to do or equally judge someone I don't know as a monster.
My overall point is this, I have twice in 20 years had comments at work about being a Jew, one by someone who thought it was ok to tie into banter about Spurs, I dealt with it and accepted the apology, having it know it was ok. But from then on it was dealt with, if someone felt the need then after to go after the person to have them sacked or push for more than I was willing to resolve I would have been more offended than the original offence. I get that there are different scales and this is in the public eye, but I think fundamentally the same applies, if he apologises and she says fine, its not really anyone else's battle IMO
