Is Pride still a useful event?

I was reading a critique of Pride by Mia McKenzi in which she says that Pride doesn’t accomplish the things she needs:

What I need, and what most of the folks in my community need, is access to education, and health care, and food that isn’t slowly killing us. We need for our tax dollars to not be spent killing other brown people all over the world. We need the police to stop using our black bodies for target practice. We need…shit, we need a lot of things. And very few of them involve hot pants and feathered floats.

She continues on saying that Pride is more of an corporate event for white gays and lesbians who want to be normal, with marriage and a Subaru, not an event in which people discuss the intersections of race, gender, class, and sexuality, and how society uses them to harm people:

I just wish some of this “pride” energy (and a LOT of this Pride money) was being spent demanding justice for Brandi Martell [a trans woman of color who was murdered. And Cece McDonald [a trans woman of color who was arrested for murder after attempting to defend herself against a physical attack] . I wish all the people who care about after-parties cared about Rekia Boyd [an unarmed woman of color shot by the police].

Is McKenzie right – that, “despite what today’s LGBT mega-organizations want you to think, Stonewall was a RIOT, y’all. Not a parade.”? Is Pride still a useful event? What is it accomplishing? Do you attend? How could Pride be changed to be better activism for LGBT/QUILTBAG rights? What things would you not want to change?
