You say you didn't explicitly blame women, in fairness, you referred to 'people' not women:
It's just rather underhand when people dont confront the person at the time and let them carry on thinking everyone finds it funny and are ok with the 'tone' and then several years later deciding they're a victim.,
It's just that the 'people' in this case who are underhand and belatedly 'decide' they are victims happen to be..women.
So in fairness, you blamed 'people' and not women; but in fairness, Shenmen wasn't conjuring 'victim-blaming' out of nowhere, was she? and in fairness it wasn't an 'extreme accusation', was it? It wasn't name-calling or goady, it reacted to you saying that some 'people' are not genuine victims. That seems fair enough. You may not agree, but that's the way discussions go - viewpoint/alternative viewpoint/discussion of viewpoints..
I wouldn't agree that Shenmen's post is 'extreme', and I don't see how it shuts down balance, so if you decide not to continue this discussion, which is entirely up to you, I don't think it's fair to suggest that it's because of Shenmen's post.
It's up to you whether or not you want to continue, you seemed to have reached the end of your wish to engage, but you can always come back and explain what people you are accusing of belatedly 'deciding they are a victim', if you did not mean the women in the GW case.
