Some posters seem to be reading a different thread in their own head, in which all the sheeple are saying "Kate is so wonderful and hard working, doing her duty by slogging her guts out at Wimbledon when she's got cancer, for the good of us plebs, she's an example to us all."
Nobody on the actual thread is saying that, the pro-Katers are mostly saying "it's nice to see she's well enough to attend, I hope she enjoys it."
