‘Repost this if you hate cancer’—what the fuck is that supposed to do? If enough people like the post, cancer’ll just take the hint and become extinct?”
Those who’ve had cancer certainly would like this to be possible. But in this case, I’m going with “that would be magical thinking.”
Word is that cures for cancer have been developed, but men in black helicopters have arrived wherever it’s shown up, and promptly shut down the developers and the potential cure. People make a ton of money from cancer patients. Goddess knows how they could amass such sums, were cancer to become extinct.
