Save your breath.  We've heard all the arguments that Valentine's Day is an artificially manufactured holiday designed to bilk men out of money, just like we have heard postmodernists and humanities people (are they any different today?) argue that Communism is great, it is simply that none of the communist countries do 'real' Communism.  It doesn't matter; if you step out of line for Valentine's Day, the romantic equivalent of the KGB is knocking on your door.

But just because it is a marketing-driven, pressure-filled fabrication doesn't mean you can get away with just anything.   Writing on Real Clear Science, Katherine Dickinson notes 6 ways science totally sucks the romance out of Valentine's Day.

Bouquets of flowers?  Apparently only conservatives buy flowers for other people because progressives are all super-smart and therefore know this unregulated industry is not governed by the EPA or even the Earth Liberation Front and those pretty plants are chock full of artificial chemicals and grown using the slave labor of developing countries; kind of like everything Apple makes.  That's without factoring in all the emissions for shipping. If your girlfriend is a lefty hipster, you now have the perfect excuse to avoid the $50 bouquet.  You can buy her ethical thong underwear instead.
