There’s a lot going on here.
@Epimer noted how much lifting the ‘presumably’ is doing. But there’s other stuff in there that jars. I’ve spent quite a while re-reading it. And rather than tediously dissect it here, I’m just gonna summarise that it’s a very tabloidy piece of writing. Reads much more like something pitched to persuade than explain.
Which is not to take away from the writer’s lived experience, or their intended message (after all, they weren’t too know it would be posted for semi-public consumption). It’s just to say that I’m ultimately left with way more questions than answers after reading it.
edit, in light of seeing the post immediately above: No aggro at all intended to ya kermy, just trying to make sense of what is indeed a massively evocative subject. Tried my best to word my comment properly. You’ve no obligation to explain anything on anyone else’s behalf.
