No more funneling money to interest groups. I don't care who they are or what they promote. Let them find their own cash. We've got a pretty heavy bag of hammers to carry around as it is.
If the parade stands to bring in so much cash, then finding private financing should be no problem.
If the government didn't set the precedent of throwing money away, we wouldn't be in so much debt, we wouldn't be paying so much in taxes and there would actually be more money out there for people to support the things they personally find important.
As a side note, the tawdry spectacles these so-called "leaders" put on to represent homosexuals and other non-mainstream sexual preferences in this society are downright tacky and I think they have actually done more harm to the image of homosexuality than it has to better it.
If anyone was wondering why homosexuality's image hasn't progressed past this..
To this...

Pride, its partisans and those of similar organisations and events are the reason why.
Looks like you're a don't ask don't tell kind of guy. Homosexuals should not be seen?
