Oh, come on. Really? You don't think it's out of character for Kasumi to slap Akane? Especially when Genma deserves it even more for being so, so stupid as to take his son off to Jusenkyo and then not explain the circumstances in the postcard he sent, leading to the confusion in the first place.
See, the post just before that last one pointed out why some people don't take "Akane defenders" seriously. This is why I can't take "Akane attackers" seriously. Because so, so often their arguments get wrapped up in attacking her that they don't also attack anyone else that might deserve it. I mean, you're expecting me to call out Ranma in this situation to defend her, right? Nah. He was a bit shy and awkward, didn't really know the best way to explain something so completely bizarre to people that had probably no experience in magic before... Leading to the worst possible way for them to find out. I suppose that is technically his fault, but I don't put any blame on his feet for acting this way. It's a perfect reasonable thing to do. Much like I feel it was reasonable for Akane to have the reaction *she* had.
In order for Kasumi to slap Akane, she would have to do something extraordinary. And again this is not a defense of Akane. Remember that one chapter where everyone thought she was pissed? And then everyone* threw him under the bus, and she barely did anything to punish him while still thinking "oh dear I hope that wasn't too much". Or how about the time at the end of the second chapter where Akane dumps a table on Ranma? No real reaction from her. In order to get Kasumi to slap pretty much anyone you're gonna have to work for it.
As for the fight between Ranma and Ryoga, leading to her hair getting cut off? Hypocritical in what manner? I don't see it. Stupid, certainly for putting herself into the middle of that fight in the first place. It wasn't really her fault her hair got cut off either. Ryoga was carelessly chucking his bandannas around, Ranma blocked it, they're really lucky nobody got actually hurt. If anything having her hair cut off should have been a wakeup call that they needed to stop. Especially Ryoga. Again, not blaming Ranma for this, Ryoga was the one tossing around dangerous projectiles (including his umbrella, which he spun like a top).
Actually, Ryoga really was an asshole in that fight now that I think about it. He didn't seem to give a single solitary damn about collateral damage until, whoops, sliced that girl's hair off. Ranma was being pretty heroic trying to fight him while keeping Akane out of harm's way. On Akane's part I guess slapping him was maybe a little too much, when all he did was block the bandanna and argue the toss with her. But hey! She has good reason to be upset under these conditions. She was growing her hair out to try and get Tofu's attention, having it suddenly cut off like that must have been kind of upsetting.
And you want to have her get a slap when she's already emotionally vulnerable? Christ's sake, forget the fictional characters for a second and where's your empathy?
The more I think about it, seems to me that the thread title should be "what if every character in Ranma 1/2 got slapped?" 'Cause they all have it coming to some degree. Except Kasumi, whose worst crime is being an enabler.
*I should note this includes Akane, by the way. One of the moments I really hated from her. It was played up for comedy, as in "oh, Akane's coming to save Ranma from everyone else" and then she joins in pinning the blame on Ranma. He was pretty much the only one that didn't come out looking like a shitlord in that particular circumstance.
