But that's just the thing. If anything, I find it much worse to slap a child than to slap another adult, even if that adult is physically weaker.

But you have a point. I suppose today more people still think that it's acceptable to slap a child (especially a child like Joffrey) than for a husband to slap his wife.

Anyway, it's just one example among many. This fandom is fairly big on judging characters for things that are perfectly okay when someone else does it. :/ And of course we're all guilty of that to a certain extent, but sometimes it's just ridiculous.
