I haven't assumed anything; if you look back in any of my posts I've never once claimed she does know Churchill is dead.

You, however, have made the claim that she doesn't a number of times. That is you making an assumption and then getting all het up about it.

I've not read the comments on that link on a terribly designed website run by a man who was described as 'Australia's latest nutjob', but if they're also stating that she doesn't know Churchill is dead then yes, they are also making assumptions.
