F4 is gradually upping the ante, here.
If you have a child, and your child was raped or sexually assaulted, that is of course terrible.
But I must draw everyone's attention to the fact that we are in a cycle of "false assertion, debunk, false assertion, debunk, false assertion, debunk..." here. F4's "child" first appeared in about iteration 3 or 4 (you'd have expected the child to be mentioned much earlier) and at that point was subjected to bullying. Here we are on iteration 6 or 7, and F4's child is now a rape victim.
I repeat, if F4 does in fact have a child, and that child has been raped, that is beyond terrible. But, on the tenor of the thread so far, I do not think this is actually true.
