For some of us, today, Valentine's Day, can be as depressing as other holidays that are centered around heterosexual love and family relationships. In some ways, this day can be even worse than Christmas and Thanksgiving are because almost all of its trappings are based on cis- and hetero-normative (I promise not to use that term again for a long time) rituals and behaviors. And the same sorts of people who accuse us of wanting special treatment make a point of being as obnoxious as possible when fondling each other in places that charge too much for oysters and champagne.
Plus, this "holiday" is even more commercialized than the others. I take that back: The others were hijacked by corporations to make people feel guilty for not buying their useless, overpriced shit and giving it to people they pretend to care about. Even so, most people have some vague notion of what those holidays are supposed to celebrate. On the other hand, Valentine's Day as we know it, is entirely a creation of the greeting-card, candy, lingerie and other industries, almost nobody realizes that this day was originally a feast day for St. Valentine, who has almost nothing to do with the notions of "love" fetishized on this day
To counter this, artist Alexandra Dean Grossi has created a set of free e-cards celebrating "All Hearts Day":
