It isn't homophobic, it's a realistic assesment provided for the benefit of those people who don't want to subject their kids to something objectionable just to prove how tolerant they are.
Very true, but the typical gay visitors at Disney throughout the year aren't the same as the typical Gay Day visitor. They are going
because they are gay and to prove a point. Many feel they can't prove that point without openly, and graphically displaying their sexuality. That is an entirely different mentality than a gay couple who is going to Disney to enjoy the parks. Considering gays are not banned the other 364 days of the year, what do you think is the motivation for them to attend Gay Day? It is an open invitation to behave much differently than they would any other day of the year.
If 20,000 hetero swingers all decided to storm the park one day a year to show their cumulative strength - what type of atmosphere do you think would exist?
If you have a problem with gay people, don't ever go to Disney - in fact, don't ever leave your house. But even if you have no problem with gay people, it's alright not to want to spend your vacation when there is a huge number of people that are there to make a point as much as they are to enjoy the parks.
Don't let the militant politically correct crowd guilt you into putting your family in an uncomfortable situation - or suggest that you'll likely just see some innocent handholding.
