Can't you? Or to put it another way: in the face of Reason, can the emotion even remain?

If you rationalise and understand the triviality of the situation and the ultimate stream of nonsense that the App apparently is, would this affect you?

It seems one would be emotionally affected upon _failure_ to make this rationalisation.

I'm going to extend my earlier comment to "clearly you've never been clinically depressed." The attitude that "you've got nothing to be sad about, rationally speaking, so logic your emotions away and cheer up!" is a factor in an awful lot of suicides.
