A UK charity is taking this approach to fund raising.

Compare these two adverts -

"Not Alone", MacMillan Cancer Support (http://www.youtube.com/watch?v=MLpS97XA5VA)

"Cancer, We're Coming For You", Race for Life (http://www.youtube.com/watch?v=GWJEmMDQXoA)

Yes, fuck cancer.

I'm not sure if you understand what MacMillan is about, but you're comparing apples and oranges here.

"Fuck Cancer" is all well and good... but MacMillan's work isn't about finding a cure, it's about easing suffering. They provide support and care to patients and their families, "Not Alone" sums them up pretty perfectly.
