I’d consider them adults, but developmentally delayed and cognitively ill-prepared for honest dealing. They call her a whore because, really, they haven’t thought completely through the issue or their response, so their immature knee-jerk response is to toss out an easy insult that doesn’t even fit.
I got in trouble in second grade for calling my friend Tim a bitch. I remember it like it was yesterday. I was mad at him for taking the dodgeball we were playing with and throwing it across the pavement. Our teacher was standing right there. I was mad and the first thing that popped into my head was to call him a bitch, so I said it, and had to spend a few more recesses inside not only for saying it, but for being dumb enough to blurt it out right in front of the teacher.
These debates about serious issues are also on that same level.
They might as well call her a fag or something else nonsequitur. None of it makes sense, because none of it from them has been completely thought through.
