Persecuted groups have often been made to feel ashamed of who they are, whether it is their race, ethnicity, socio-economic status, or sexual preference. Although the original march was on the anniversary of the Stonewall riots, and were organized as a march to demand fair treatment, it grew in to something that I think showed gays that they are not alone, and should not be ashamed of being who they are.
I also believe that the celebration sometimes gets hijacked by people who want to display and perpetuate every vulgar gay stereotype, much of which belongs behind closed doors, rather than on display for the public to see.
Instead of 'treat us fairly, we are just like you', it has grown to into 'look at me! I'm in drag!', or 'check out my arse in these chaps!'
I know gays that hate that aspect of the parades, as again, they only serve to perpetuate negative stereotypes.
I think a more appropriate pride parade might show gays as normal working citizens.

Yes, our parades have people in drag, leather, and next to nothing. But if you watch it, you will see that the majority of the people are just regular people. You never see the media covering the two moms walking w/ their child because that doesn't cause the reaction a man dressed as a woman does, or the near naked men dancing and prancing around.
While I don't dress in drag and have enough modesty to wear clothes that cover my body, our parades are about our unity as a community. It takes everyone to make up our pride marches, cuz it won't be as fun without our drag queens and kings (they are entertaining).
