Mother's Day - Take 2: Another side of the coin

This mother's got a point, too:

Why I hate Mother's Day

There are several good points in this article, like the one about how celebrating Mother's Day only perpetuates the stereotype that women must be mothers to be appreciated and feel complete. But of course, there are plenty of readers and commenters who also feel offended by the bitterness of the author's tone, because, these are our mothers we're talking about, and how can we not acknowledge our dear mothers (ok, I work in mental health, I know how... but you get the point).

So how do you feel about Mother's Day? Is it an important step in feminism to include it as a national holiday, or is the whole thing a sexist Hallmark invention? Should we stop caring about the politics and just appreciate our mothers already, or is it simply silly to designate one stinkin' day for mother-love?
